I custom built a frame table for the project.

12' x 58" table made from 3" x 3" x 3/16" square tubing

2" x 3/16" round tubing legs with 3/4" bolts to level the table. It has six legs. The center two legs will make up for any deflection. According to my calculations, a 500 lb point load in the center of a 10' span will cause a 0.2183" deflection. This is not near the yield for 3" square tubing, but I'm not going to take any chances.

Each corner leg has a mounted piece of 1 1/2" tubing to hold a heavy duty 8" scaffolding castor. This will allow the table to be moved with ease. Once the table is in place, it will be jacked up and I can remove the wheels.

The 12' length of the table has 1 1/2" x 1 1/2" x 3/16" angle iron welded at 2" from the top of the 3" x 3". This will allow for 2" x 2" x 3/16" cross members to be placed anywhere along the length that is deamed necessary as the build progresses. These cross members can be clamped or welded into place.



In retrospect, I used the round tubing for the legs because I had that tubing on hand. If I ever do this again I will use square tubing to eliminate the need to notch all the supports. It did however give me some practice using the tubing notcher!



Here you can see the angles that support the crossmember peices.



Here's the car being mocked up for ride height. I chose the rims and tires based on the radius of the rear wheel well opening, etc. I played with the ride height quite a bit before finally deciding.



Here are a couple of pics of the body finally mounted at ride height. The wheels are removable and I have welded threaded plates on the bottom of the legs to accept 3/4" levelling bolts.
