1931 Chevrolet Five Window Coupe
Owner: Jim Heinzie, Fargo ND
Jim had the 31 Coupe for over 10 years and in several shops
prior to bringing it to us. The top had been chopped 3”, the Fat Man front
suspension had been installed and the Chassis Engineering rear suspension with
Ford 8” rear axle had been installed. Some of the frame had been boxed but not
finished.
The
early Chevrolets were still built like carriages. A completely wood frame was
built and then the sheet metal was nailed to the wood frame. This is why so few
early Chevrolets are around, there is nothing but a pile of tin once the wood is
rotted away
This is a wood body frame put together before the metal is
attached.
.
We replaced all the wood in the body with steel which we
had to fabricate. This included the door frames, door jambs, main body rails,
roof rails, and everything else that was wood.
The front fenders, rear fenders and trunk lid are
fiberglass. The rest of the car is all steel!
The frame is the original 31 that has been fully boxed and
smoothed. The drive train is a late 70’s high performance 350 from a Z28 and has
been fully rebuilt. A 350 Turbo Automatic puts the power to the 8” Ford rear
axle.
We have 1500 hours of labor, if not more, into this unit
plus the body work, paint, upholstery work and the work completed before we got
the unit.
Body and paint work was complete by Andre’ Arneson at
Intense Collision Center, Fargo, ND. The upholstery work was completed by Billy
Phillips of Billy’s Custom Cover-up of Kindred, ND.
Following is the picture history of the build up.
|

|
This is how
the 31 looked when we first saw it in Jim’s garage. The body was flopping
and the doors and trunk were not mounted. |
|

|
No floor or
structure to keep the body square. It actually looked much better than it
was. |
|

|
The front
suspension and rear suspension were mounted, that is a big block firewall.
|
|

|
The first
thing we needed to do is to brace up the body and get it straight. Parts
were fabricated and set in place. Everything was measured, measured again
and measured once more.
The door jamb
is 16 gauge sheet metal bent to shape. |
|

|
We started on
the top, got it squared up and then installed the hand formed bows to follow
the roof contour. |
|

|
This inside
shot shows the tube steel structure. You can also see the tube structure in
the door post to support the door jamb and roof. |
|

|
Parts were
only tack welded in place until we were sure it was all square and straight.
Even then it is triple checked. |
|

|
Once the body
had some structure in place we started on the suicide door hinges. We had to
build the door structure and support first, then add the hinges and hinge
support. |
|

|
The 16 gauge
jambs were formed around and over the hinges to add support and provide the
finish surface. |
|

|
Here the body
is on a frame jig to assure a square setting. The suicide doors are fully
mounted and swinging. The doors have a natural tendency to swing out because
of the hinge angle. |
|

|
Next is the
front cowl and dash area. There were no support structures here other than
wood. We added to the dash and created a tube frame structure to support the
cowl area. |
|

|
This shows
the cowl/dash support. We wanted to add defrosters some how, so we boxed the
tubing with sheet metal to form a closed box. An inlet tube was added in the
back and slits were cut on the top by the windshield. This set the dash
panel back about 1”. |
|

|
The back end
need lots of squaring up and straightening to get the fenders and trunk lid
to fit. We had to undo some of the previous work to get everything to line
up. The deck lid is fiberglass and we made steel mount plates for hinges and
latches for added strength and glassed them to the lid. |
|

|
The rear pan
which was hand formed is in place and the trunk lid is getting really close.
|
|

|
Here is a top
shot of the door structure, rear and front jambs and window trim in place.
|
|

|
What the
front cowl/dash and front jambs look like with the doors closed. |
|

|
The trunk
latch is fabricated and the lid side drain/strip channels are hand
fabricated using a stretcher/shirking tool. |
|

|
The body is
getting there, the roof bows are in, doors hung, jambs completed and trunk
deck fitted. |
|

|
Here the door
hardware is mounted. Power windows are added using Plexiglas as the trial
fit piece. Electric dead bolts are added for safety to keep the suicide
doors locked when driving. Everything is run through relays so we can
operate them with manual switches as well as remote operators. |
|

|
Now to the
chassis, here Kelly is fitting up mounts, plating the rest of the frame and
adding other components.
The 350
engine will be fully rebuilt once everything is fitted. |
|

|
The fire wall
was fabricated from 16 gauge and installed as a complete unit that was fully
welded to the body. It is defiantly a tight fit for the engine. |
|

|
Here the
floor has been installed over the floor braces, the transmission tunnel is
fitted, brake master cylinder access is in place and were getting ready to
fit the seats. |
|

|
We are using
a 1932 grill shell and hood on a 31 body and frame. The 31 had a flat bottom
hood while the 32 had a curved bottom hood. These hand fabricated steel
units will act as a filler bar for the hood as well as the hold down and
mounts for the front fenders. |
|

|
Power seats
from a Chrysler will fit in the narrow body. Seat mounts are fabricated and
welded in place. We prefer the studs on the seat for easier mounting. |
|

|
With the
engine out we can fit the front fenders and front end metal. Troy is doing
some finishing work on the firewall. Kelly might be doing a ballet? |
|

|
The trunk
deck, rear pan and rear fenders are mounted and primer work is started.
To get the
rear fenders to fit right we had to pull and push the rear quarters every
which way and stretch them to get them back in shape. |
|

|
This shows
the dash, steering column, jambs and latch relief’s mocked up. The switches
on the edge of the dash are for the door, windows and dead bolt locks. |
|

|
With all the
sheet metal mocked up it looks like a car. The light bar is a 30 Ford and
the front pan is a Chevy truck unit. The fiberglass front fenders are
supposed 31 units. Radiator shell and hood are 32 units. |
|

|
Strip it back
down and start the body work. The visor is welded to the body. |
|

|
More body
work to get it all straight. The trunk lid looks pretty good. Taillights are
frenched Ford units. |
|

|
More body
work shots. Put it on and take it off. |
|

|
The body is
about as far as we will take it. It now goes to Andre’ ant Intense Auto for
final prep, paint and buffing. |
|

|
Back to the
chassis. It is smoothed and painted chassis black. Yes it is upside down in
the shot. |
|

|
Right side up
the chassis starts going together. The fully rebuilt 350 engine and 350
transmission are mounted along with all the other components. |
|

|
Here we can
see the master cylinder and booster mounted along with the engine and
transmission. An transmission oil cooler will be mounted just behind the
transmission mount on the frame rail. |
|

|
At Intense
Auto, the body is prepped and has been jammed with the Candy Apple Red. |
|

|
The interior
of the body is cleaned, seam sealed and coated with bed liner material to
really seal it up and help with sound. Note the door jams are painted. |
|

|
The boss at
work, Andrea’ doing some hood prep. The inside of the hood is also painted
with bed liner to help with looks and durability. |
|

|
The
fender/hood filler bars, dash panel and hood doors prepped for paint. |
|

|
Red parts!
The Candy Apple Red is a tri coat. A silver metallic base is laid down
followed by several coats of tint. The more tint the darker the color. Then
several coats of clear. |
|

|
Josh and Brad
inspect the painted body in Andrea’s paint booth. Just wait till this gets
out in the sun! |
|

|
One very nice
front fender, painted and buffed! |
|

|
One of
Andrea’s team hard at work. |
|

|
Back at the
shop, on the chassis with fenders and running boards on. Insulation is
installed, cowl lights are on and wiring has begun. |
|

|
It’s starting
to look like a car but has lots of stuff all over the place. Still a long
way to go. |
|

|
The fuse box
is mounted in the rear panel so it can be accessed from the trunk or from
behind the passenger seat. Wiring is fun! |
|

|
Getting
there, taillights and trunk lid in place, it is starting to look like a car
again. |
|

|
More work
done but still not complete. We have had the engine running and ran in the
cam already. |
|

|
More items
added, the doors are getting filled up.
That is a
55 Mercury
Sunvalley on the lift. |
|

|
First time on
its wheels and is it LOW! Too low, we had to change the springs to get it up
so the wheels would turn. About 1.5” between the floor and the front pan.
|
|

|
Ready to run,
the American Racing wheels are on. 16” rear, 14” front with 60 series tires.
|
|

|
Outside,
running and ready to go the upholstery shop. Note the weather stripping and
the door mounted mirror. A leather covered aluminum steering wheel. |
|

|
This is what
the door looks like with glass and all the wiring and gadgets installed.
If you look
closely at the bottom hinge you will note the steel tube wire run that is
part of the lower hinge. No flex tube or springs for wiring here. We do this
on almost all of our units. |
|

|
Almost
completed car with wheels, front bumper and exterior pretty well done. |
|

|
One more look
from the right side. We took the unit on its maiden run to a NDSRA meet in
Valley City and got the state pick! The interior was not done and neither
was the exterior! |
|

|
The rear
bumper has to go on, but will wait until the upholstery is done in the
trunk. No need to knock your shines on it. |
|

|
Billy at
Billy’s Custom Cover-up made all the interior panels covered them in Camel
ultra vinyl. Note the texture in the side panels. |
|

|
Billy had to
create the headliner and the rear panels. The square panel is the fuse box
access from the passenger side. It folds down for easy access. |
|

|
The
radio/stereo is mounted on the roof and dual windshield wipers are wired
together and work of the toggle switch on the side of the radio box. |
|

|
Completed
interior with power seats installed. This is very nice, quiet and
comfortable. |
