I have my 55 Chevy in pieces and it is time to think about the roll bar/cage. With a mildly built 454, I am estimating mid to possibly low 11's. I had thought to attach the B bar to the mid body/frame mount by welding a larger plate to the frame and through bolt it. Then run the rear supports into the trunk and bolt through to structure welded across the frame in that area. Perhaps concurrent with shock mount kit. SW Racecars has a roll kit with 1 3/4, .134 material for $170. Or, they have a 1 5/8 cage kit for $250. Anyone know about this manufacturer? And any ideas or plans for the 55 Chevy bar/cage would be greatly appreciated. This will be a D/Gas car or possibly C/Gas.
