where are you reading all this, is it on a SFI 25.1 spec??
SFI 25.''4'' spec. Print date is june 14, 2002. But I emailed them a couple months ago and they said it was still current. According to the material list the forward cross members 6A & 6B can be either 2''x3'' .083'' or 1 5/8" .118" round. I didn't find that until tonight. If I bend them for exhaust clearance looks to me like I then have to make the "Frame rail to rocker bar" floor sheeting out of .035" steel?? I think using the 1 5/8" round will give me the header clearance I need. Can the roof diagonal and the windshield halo bar be bent to conform to the roofline?
