Okay guys:
Wanna share your technigues for mounting the body to the pan?
I have a 2" box steel rail running around my pan and plan to weld 3/8" nuts into the top of the rail that will be flush with the top surface of the rail. A roll bar will be probably be welded to a 1/4" flat plate that will sit on top of the fiberglass lip running around the inside of a Berrien body. Not sure how many bolts will hold the stuff down, but I just talked to a guy that has a Manx-Type buggy that he races, and he's using four bolts to hold his body on!
