Money making distractions – Part 5 (more funds for the 1929 Ford Roadster hot rod)
The 1986 Corvette Indy Pace car convertible was just about totally dismantled now and it was getting very late in the fall. During one of my rounds cleaning up leaves in the yard, I twisted my back resulting in very serious lower back pain. Having major mobility issues, work in the shop on the hot rod, and removing parts from the 1986 Corvette had come to a screeching halt. With winter and snow not far away, I felt that the stripped out shell of the 1986 Corvette needed to go. There was not much left of the 1986 Corvette convertible. I started advertising in a number of local papers. Maybe somebody would have a use for what was left of this poor old Corvette? I thought I would give this a try before I would have the car hauled away to the dump. About a week passed by and a fellow called asking about it. He had a 1986 Corvette that was hit in the front end. Mine was hit in the back end. This fellow had a plan of cutting the two cars in half and reconnecting the good parts of both cars together. I thought this was a bit excessive but it is a good thing for folks with those kinds of ambitions. If it were not for these very ambitious and skilled enthusiasts, there would not be as many old restored cars or vintage vehicles on the road today. This is truly a labour of love.

We made arrangements for him to see the car and we made a deal. He gave me $600 for what was left. This put a huge smile on my face even with the pain in my lower back. The following week he came to pick up what was left of this poor old 1986 Corvette. I was still having problems with my lower back. The fellow that bought the Corvette was having similar problems with his back. It must have been interesting to watch two old guys with back problems lift the car onto the U-Haul trailer. I was somewhat amazed how light the stripped out shell of the car was. That was a real good thing for us. It was fortunate that this fellow bought his son along to help out. This did make everything slightly easier. The 1986 was now out of the driveway. My wife had the biggest smile of all as she referred to the driveway as a bit of a wrecking yard. I must say, my wife has been a real sport through my adventures with cars. She just shakes her head in amazement that thought that I have been able to make pretty good money at this. The bottom line is that anybody getting into this hobby had better have the support of their partner, otherwise there will be problems, and life is too short for problems.

He had a another Corvette that was hit in the front. This one was hit in the back. He wanted to cut the two cars in half and make one good one. Truely a labour of love.
In a few days I will continue with the work on the front suspension for the 1929 Ford Roadster hot rod using the suspension from the wrecked 1986 Corvette Indy Pace car convertible.

Chassis / Frame Design for the 1928 to 31 Model “A” Ford Street Rod – Part 5
Now it came time to work on what I thought was the most difficult part of the chassis, the front suspension. For the first attempt at this I decided to use exactly the same wheel base as the stock Model A Ford from 1928 to 1931. The front of the frame rails already had the same shape as the stock frame. The only difference was that my frame rails were made of 2” x 4” x 0.1” rectangular tubing. This would make a much more robust frame or chassis. You have to remember the original Model A Ford from 1928 to 1931 did not have much horsepower. I will be using a stock 1986 Corvette engine with over 200hp and over 200 ft-lbs of torque. This is a very important consideration in the hot rod frame or chassis design. The stock Model A Ford from 1928 to 1931 also had all of the cross members riveted to the side of “C” channel frame / chassis rails. Over 70 years these rivets loosen and the general strength of the frame / chassis will be compromised. The frame / chassis I will be designing will not used rivets or “C” channel side rails. All of the required cross members will be welded to the rectangle 2” x 4” x 0.1” rectangular side frame / chassis rails. Just pick up an original Model A Ford from 1928 to 1931 and watch it flex. The hot rod frame / chassis I am designing, using the C4 Corvette suspension components will not have the same flexing issues.
C4 Corvette front cross member stripped down and ready to have measurements taken from. The new street rod cross member will not look anything like this.
I needed to measure everything you could possibly imagine on the C4 Corvette front suspension cross member. The cross memeber comes out of the Corvette as a complete unit. In my case, it was removed from a 1986 Corvette Indy Pace car convertible. I am sure that the Corvette engineers never dreamed of seeing their cars put to this use. Corvette suspensions used in hot rods and custom cars.

The obvious starting point would be to measure the width of the C4 Corvette front cross member at the point where the upper control arms are attached. This measurement was slightly wider than the stock Model A Ford frame / chassis from 1928 to 1931 at the front wheel base center line. I thought that I would mount the controls arms in a similar fashion as the stock C4 Corvette did. It seemed reasonable to make brackets that would mount to the outside edge of the new frame or chassis rails. This meant making the frame slightly wider. In order to make sure this would not create a problem or look terrible when the body was mounted onto the frame, I widen the front frame and quickly lifted the body on to the frame. At that point I realize this would all work out perfectly.

Now I needed to establish the front ride height. Having the entire C4 Corvette front cross member dimensions in hand, it came time to mock up the front suspension. Using some 6” x 6” x 0.25” angle iron as temporary front cross member for the lower control arms was created. The width of the lower part of the cross member was matched to the inside mounting width of the lower control arms removed from the C4 Corvette. It was assembled using c-clamps and tack welded in place. A bracket was created for the upper control arms using angle iron. I clamped these brackets to the top the of the frame rails. Now it came time to mount the C4 Corvette front suspension parts onto the frame mock up and see how everything would like. Remember, humans are very visual, and since I am a professor, I realized that most of what we learn or process would be through our eyes. The brain tends to process the visual information much easier and faster. This is why I needed to mount the rims with tires to the suspension and have the body sitting on the frame. I would quickly see how everything would look. I even used an old Jaguar rear coil over shock to visualized possible mounting schemes for it.

The set up for the front suspension is all very temporary, and is only used to evaluate the ride height and overall look on the hot rod frame / chassis.
Come back next week to see how this progresses more towards the final product and finished state. Of course you can have an advanced look at the completed hot rod frame / chassis for my 1929 Ford Roadster. Just go the “PAGES” section new the top right of the screen and click on “Preview of the 1929 Ford Chassis with C4 Corvette suspension.
This frame / chassis will work for any Model A Ford from 1928 to 1931.
