I want to do a 6 pt roll bar in my 79 Cutlass wagon, not worried about being NHRA legal, just want something to stiffen the chassis and have a little safety for autocrossing. I have it designed so that it will not have any interference with front or back seat and I can buy straight bar stock locally and put minor bends in it at school. I was thinking to start with a pre-bent main hoop though. Wondering what manufacturer's hoop fits tight and clean? Any recommendations?
