50 Chevallac Frame

 "Chevallac" front clip installation.

      Ken wanted his fathers 50 Chevy Pickup chassis to have a smooth ride and better handling. A Cadillac front clip (yes 76 Cadillac Seville) was acquired to be installed as well as an S10 rear axle and springs. He was originally going to run a GM V6 with 700R transmission. This was later changed to an LT1 350 with some go fasters added.  Here is how we installed the clip, rear axle and other items.

 Ken also wanted something unique in the appearance of the truck. We settled on the look of the Chevrolet SR10 sport truck. After all, the SR10 is styled after the 50 pickup! You will see a great deal of work going into the front fenders and grill on this truck. We also chopped it 2”, filled and rounded lots of stuff.

 The truck will have AC, Power Steering, Tilt Steering, killer stereo, cruise, power brakes, power and remote windows and locks, a power box cover and leather 8 way power seats.

Enjoy the tour!  

This is the stripped front frame before the front straight axle is striped off.

The donor, a Caddy front clip with massive bumper and stuff. This is a 1976 Caddy Seville front clip.

After lots of measuring more than once, the cut lines are decided upon and a template is made to transfer the angle to the pickup frame. Here the template is marked off on the frame and everything is squared up to assure one cut. The entire front suspension is taken with the frame.

 

A closer look at our cut lines

The Caddy front clip is ground and prepped for cutting.

 

After lots of alignment and triple checking the Caddy front clip is welded on. This is one big ugly front end!

 

 

This shows the welds and plates added to assure a solid joint. This will be ground and look like a factory job.

 

Model T rear axle is in the picture

Now the S10 rear axle starts with lots of measuring. We had to move the spring mounts inside the 50 frame and create "boxes" for the             rear mount.

Access was needed for the outside of the shackle so a curved access was made.

The front shackle fit under the frame and required some trimming. The 50 frame is wider at the rear than front.

Here the rear suspension is in; note the complete box on the right side, left to be finished. The gas tank is an S10 and we used the stock mounting hardware.

 

A 65 Impala is sitting next to it.

 

Another shot from the front of the rear axle. Note the new bar for shock mounts

One thing we added was the frame stiffener. This ties the front A arm mount to the rest of the frame and left and right rails together to take the twist out of the frame.

 

We had figured out where the radiator mount was on the original frame and cut the bumper horns off and got the radiator back in the same place. The front fenders mount off of this piece.

The Chevallac is born. Caddy front clip with power steering on a 50 Chevy Pickup with V6, 700R, S10 rear, gas tank and frame stiffener all in place.

 

It’s a year later and we now have the cab in the shop set on a wood frame to keep it level and square. We will be replacing floors, cab corners, chopping the top, changing the dash, adding latches and installing speakers and AC.

Another shot before it is fully stripped.

This is the floor kit from Bitchen products. It will provide a completely flat floor.

First is to cut out the old floor. Here the toe board and floor on the passenger side is removed.

This is the pile of stuff removed from the cab including the passenger floors.

This shows the toe board mocked in place and the cab mount tacked on. The inner kick panel has already been replaced.

The toe board, inner kick panel and cab support are in place.

A new cross brace comes with the kit and is in place along with the floor board, toe board, kick panel and cab support.

A filler piece is included to help strengthen the toe board to kick panel and cab support.

Now the outside cowl panel can be removed at the factory seam. Lots of lead filler in these old units from the factory.

On the new replacement we cut out the vent lovers and filled the vent hole before we replace the panel. The real trick is refitting the factory joint.

 

We also filled the vent openings in the kick panels as well.

No more gas tank behind the seat so the filler hole has a plug welded in.

Progress, we now have the drivers’ floor, toe board and kick panel installed.

Both passenger and drivers floors are in. We have also filled all the holes in the firewall other than those we will be reusing.

The transmission tunnel is in place and the front floor is complete.

Now for the drivers’ side cowl panel. We ordered the new panel with out the vent. You can see the inside vent is closed up and welded.

With the rear floor tacked in place we tipped the cap on its front to install new cab corners, inner cab corners and weld the bottom of the floors.

 

31 Chevrolet Coupe body is in the background.

The rear floors are welded in place. The back wall braces will be rewelded once the cab corners are finished.

One item we always rebuild is door hinges. The old Chevy pickups did not have much of a wear surface for the pins and usually rusted so the brackets are always worn. The brackets were drilled for new GM brass bushings and pins.

 

A great deal of heat was applied to get the old pins out.

Here is a finished hinge with new brass bushings added and new pins. There is an oil access hole in the hinge but it is rarely used on any of these old pickups.

On the chop we plan on taking 2” out of the windows and hope to get a full 1” out of the dome of the roof. Here you can see the 5” dome height.

Ken wanted a smoothed dash with very little on it, so everything will get filled.

This shows the glove box, ash tray, radio and speaker holes fully filled with new metal.

The green tape shows our intended cut lines for the chop.

This is one haircut! The skin will need to be stretched so off it came.

Here is the skin after its cut off. That’s a 54 Merc Sunvalley skylight top it’s leaning against.

Any time you’re cutting a roof you need to brace the cab. If it moves any at all you will have more than your share of problems getting doors to fit!!

This shows the roof structure cut off. We use the section we take out as a “sleeve” on the inside to help with alignment, welding and strength.

It’s a convertible!

We welded the roof structure back on with out the skin and refitted the door tops first. It’s much easier to get at the structure from the back to work metal with the skin off.

This is the back corner fitted and welded. Some pie cuts are needed to help with alignment.

Here the skin has been pulled over the roof structure and slightly flattened. We only came down about 1/2” instead of the full 1” we wanted.

The back seam needed a backer to take up the gap and keep some curvature.

This is the lower dash extension piece prior to cutting holes and final fitting. It will be fully welded to the bottom of the dash.

Here is the lower dash installed. We did modify our initial plan for rectangular AC vents and went to round ones. The stereo and AC controls will go in the middle holes.

We wanted to hide the speakers as much as possible yet get the best sound. The rears are 9 x 11 units and will sit at an angle facing the center of the roof.

This shows the two rear speaker mounts from the front.

This is the can for the front speakers, 5” and will be hid under the dash on the kick panels and above the toe board.

The cab has now been put on the completed chassis for mount positioning and the front sheet metal has been installed.

 

The tape lines are possible cuts we might make to reshape the front end look. Our objective is a cross between the 50 Chevy and the new Chevy SR-10.

To get rid of the “frog eye” look we will flatten the fenders. The top is cut out to provide a flat look and bands are taped on to get the initial shape of the new fender top. We will have some metal rolled for the top and may have to hand fabricate the front part.

A buck is made from plywood to provide the shape of the new fender top. When we roll the sheet it will have to fit this buck just so.

On to the doors, we threw the old latches which have always given us problems with remote door openers. The new bear claw is installed and the original inside door handle will be utilized.

The new bear claw pin is installed. All of this will be ground to look factory.

The inside rear panels are finished welding and ground down. A skim coat of fiberglass will help to seal the welds and finish it off. We will be using the rear dome light.

The power antenna is installed in the passenger side rear cab corner. We use a unit that only has the tip of the antenna showing so when done it will hardly be noticed.

Ken decided to make a power train change and go with an LT1 350 unit. So out comes the V6 and some changes have to be made.

Here the new freshly rebuilt LT1 is in place with a 700R trans behind. We had to modify the inner structure; move the transmission mounts and came out ok on the brake and other controls. The Corvette Yellow is one of the exterior colors.

Because of the cross member under the engine we could not use the Camaro AC and alternator mounts. Some aftermarket steel brackets and a small power steering pump create the serpentine belt drive system. We also had to go with a Sandan AC unit and older style alternator to fit the brackets.

The fenders are mounted, intake installed, radiator in and hoses for water and AC are run. The wire is the engine harness and will be connected to the main harness upon final assembly.

To the back end. The brake and fuel system is tested and holding pressure, rear wire harness is run and we are ready to mount the new box.

A quick look at the steering column mounting and the engine computer is mounted inside just above it.

Remember the big holes in the fenders. We had 16 gauge sheet rolled to fit the buck and here the driver’s side is tacked in place. This will give a flat top fender with some durability.

Here is a look at the passenger side before it is cut and welded in place.

The front part is from 20 gauge and is one piece. It was pie cut and spotted in place to make the curvature.

This is a mock up with tape and headlight rings taped on. We will retain the lower 3 bars and cut them at an angle. The top bar will be fabricated and go just above the head lights. Headlights will be lowered about 6” from the original location. The front lower fill pan is a fiberglass aftermarket unit.

Here the front custom bar is starting to take shape. This is 16 gauge materials that will be shaped and welded into a single removable unit.

One more look at the initial part. Does it start to take on some SR characteristics?
