Inline Tube - 1970 Cutlass W-31 Restoration - Final assembly

Inline Tube 1970 Cutlass W-31 Restoration - Final Assembly
.JPG)
It is 8 am in the morning at Wings Auto Art and the car is in pieces. The
body is on the frame cart and all the components are detailed and ready to be
installed. One guy is working one getting as much on the body before it is
mounted to the frame. All the fire wall parts including the heater box, wiper
motor and other small items are put back on the car.

The engine is quickly mated to
the trans and ready to be assembled in the rolling chassis. The second photo
shows all the parts and the body, frame and engine ready to go back together.
.JPG)
The engine and trans are now lifted, ready to go in the
frame. A few minutes later the fit has started.
.JPG)
After a few small adjustments the engine and trans are sitting on the frame.

Next the body waits in the background on the lift, ready for the reunion.

The firewall is starting to come together. The bottom of the car is semi - gloss
black and the firewall is a flat black and the heater box stands out in the
gloss black. All these parts were made at different factories and the colors
vary.
.JPG)
The frame is rolled under the body and it takes a few minutes to get it all
lined up.
.JPG)
The body is now lowered and the frame is adjusted to get it just right. With
final adjustments made the body is set down. The very front bolts are put in
first and the very back follow. We check both sides and front and back to make
sure it is all square. It is perfect - this will help to make sure the front end
sheet metal fits perfect.

The Inline tube gas tank is prepped and ready to go in. A few last minute hoses
and wires are run and the tank is ready to go in. The straps are in place and
ready for the tank.
.JPG)
The tanks bolts in with no problems. The tank is separated from the body with a
inline tube gas tank pad. you can also see the inline tube gas tank stencil,
shocks, and detail stickers.
.JPG)
The inline tube front parking brake cable is run
from the frame to the body and snapped in. The inline tube firewall stamps are
applied. These are the little details that make a super nice restoration.
.JPG)
Everything went pretty fast to this point but the dash will always slow you
down. It take hours to get it all back together. We page through the inline tube
assembly manuals back and fourth until we get every piece in the correct spot.
It is now the end of day one.
.JPG)
Day 2 begins with putting all the firewall components in place.
The inline tube master cylinder, brake lines and valves are ready to be
installed. The fit is perfect and the install is quick and easy.
.JPG)
It looks like a real car again . The carpet gives us some fit trouble and take
lots of time to get it in right and flat. We only have 4 weeks to get this car
done for the nationals and there is a long way to go.
.JPG)
The core support is assembled on the ground. The
radiator, headlights, shroud and many other parts are installed making this
assembly ready for the frame. The radiator is gloss black, the shroud natural
plastic, the core support is semi gloss black. Originally many of these parts
came from different manufactures so the shades of black vary on the gloss level.

After a few attachments to the fender it is ready to
go on the car. The emblems are reinstalled and the holes for the side marker and
emblems have to be filed for a perfect fit. The fenders had white overspray on
the inside edges. The W-31 also had a marking on the inside of the fender
at the W-31 emblem to note the location since it changed from the front to the
rear of the fender in 70 - Apparently there were a few mistakes from the carry
over 69 model.
.JPG)
The core support installs with a 2 bolts and a
few shims. Nyle and Bill from Wings are now starting with the driver side fender
and to get it just right there will be plenty of shims at the top and bottom of
the fender. The top used 1 shim the bottom of the fender used 5 thick shims and
in the door another 4 shims were used. Oldsmobile fenders were always pushed
away from the door but on this install we want all the lines to be perfect.

Here is the re-chromed rear bumper and the back side
did not get much attention from the chrome plater. This is typical so the flash
was all ground off the hammer marks sanded and now the back side will be covered
with a filler primer and Deric and Adam from wings will fill, sand, fill, sand,
prime, and paint and when it is done it will look like the rest of the car
factory freash.

Since this car is a special experimental olds it was
decided to have custom VOE mufflers made - This was a rare option that appeared
on the 70 GTO for a short time that allowed the exhaust to open at a pull of a
button to allow straight flow exhaust. Jo from Waldren exhaust work on the
project to make a special length Cutlass muffler. The rest of the pipes were
from Gardner. The VOE Mufflers sound awesome and we had lots of fun opening and
closing the exhaust.

Bill is the 3 guy to work on the column - First James
then Nyle, then James & Nyle and now Bill, then James & Nyle again. The column
fought the project for hours. Every body had a frustrating turn trying to work
out the problem. Every thing worked fine but when the 4 speed was put into
reverse to shut off the car - you were still able to mover the shifter out of
reverse. They finally got it figured out. These are the small setbacks
that take hours of time to figure out. There must be 8 hours in the column
problem.

The interior is now starting to go back in. The new
headliner is installed by Dale from LA trim - you can bounce a quarter off it.
The sale panels are also tight and the trim snapped in place to finish the
headliner. The package tray is installed and glued at the seat back edge. The
original paper shields go back in place and they still have the interior panel
ID white tag on them. The seat belts have been cleaned and the covers
restored and bolt right in .
.JPG)
Since this was such a low mile car the interior was
super so a few minor repairs were made and it was all reused. The seat frames
and the materials were factory fresh - this saved allot of time and money. The
rear carpet fit much better than the front and was installed in no time. When
cutting the sill plate edge make sure to leave enough material to go under the
rear door panel and front kick panel.
.JPG)
It is time to look at the trunk. This car had no rust issues and the trunk
splatter paint was so nice but the line work never sprayed under the matt and
the spray job was uneven from side to side. It was decided to caulk a few minor
areas and cover and even out the areas that needed attention. the rear window
interior color over spray was duplicated and you can see it under the rear
window trim between the trunk seal. There was rarely a tape or mask line on so
the over spray is also on the front cowl and the upper door jamb.
.JPG)
The spatter paint is dry the next day and covered with
matt clear to help protect it. The spatter never covered all areas and you
can see the blends all over the trunk. This is a neat progression of the process
of assembly.
.JPG)
A custom trunk matt was made and spray dyed the
correct gray/green color for an exact match to the original. This is a detail
that is often overlooked but adds most of the detail of the trunk. The jack was
refinished and the decals applied and the spare tire is ready to go in along
with the trunk seal. The seal is glued in and had the split at the latch off
center with the white and orange locating marks applied. .
.JPG)
Ofter looking at the original photos of the front end
nothing lined up but that would all have to change. The grills, headlights were
in and out several times with holes slotted and ground to get just the right
fit. These are the steps that make perfect alignment but burn hours of time
fitting and refitting.
.JPG)
The front bumper was the same as the rear and got the
same treatment of filler, primer and paint to look factory fresh. The restored
light assemblies and bumper brackets are all installed and the bumper will go on
as one unit.
.JPG)
It takes 4 guys, 2 on each end to hold align, tighten, align, adjust and final
tighten and after 20 minutes the bumper has even gap and space around all the
surrounding pieces. Since this is a Oldsmobile experimental car it had a
tag on the core support with the vin. It was attached with same rivets the VIN
used in the dash. This piece has a bit of wear but has to be on the car.
.JPG)
The front seat and door panels go in with no trouble
and saved lots of time over a console bucket seat car. You now get a final idea
of the basic interior. Bench seat, radio delete, 4 speed, rally pac and you can
see the VOE know for the exhaust.
.JPG)
It is nearly complete with us having 2 weeks to go at this point. We forgot to
order hub caps which can quickly be overlooked and stall out the assembly. This
minor item will not slow the progress but the trunk lid will. The lid has fought
the Wings guys for days. It is not going on the car until Nyle says it is
perfect and it close but he has not said the work install yet.
.JPG)
The car has now been fired and after the dyno session
there is not a single engine tune problem. Nyle is taking a final look at the
timing and idle adjustments. We are set to 36 degree advance and 950 RPM at
idle. For a 350 this all aluminum experimental engine packs 415 HP and 455 LBS
of torque at 3900 RPM.
.JPG)
You can see the Winters foundry Snowflake on the
intake and the corner of the head where there is usually a head letter.
.JPG)
One final check with the timing light and it is the
end of the work day. All the details have been buttoned up and after the
installation of the trunk lid and a few trunk lid items this car is finished
ahead of schedule - Thanks to Nyle and all the guys at Wings - Bill - Adam &
Deric
Please look at the finished car pictures in the last article.
