Bill,

I manufacture rotisseries and also have a kit with all the fancy parts (I used trailer hubs, spindles and tapered bearings so the cars roll awfully smooth). If you get the kit, you just add square stock tubing and some time and welding (grin).
Mounting to the car can be a challenge, but I would be happy to talk to you about how I do it. I have gotten 100's of cars on rotisseries (no joke, been making and selling them since 2002!).
The Jig table I made is just a rectangle about 3'wide by 16'long. Off the ground at the four corners, maybe 24" or so.
Cheers!
