Re: Roll cage build
The "D" bars need to go to a frame rail, which a unibody car does not have. So what we do is run a tube between the bottom of the main hoop, either straight above the tunnel or bend it so it fallows the floor, then weld the "D" bars to that. Also having 2 or 3 6x6 plates that tie in the floor structure at the main hoop floor connection is best. The tube size would be your standard 1 5/8" .083 wall DOM chrome moly or 1 5/8" .125" wall DOM mild steel, or a 2" x 3" .125" wall mild steel box tubing.
