I’m unable to find any company that can bend 1-3/8 x 0.058 4130 tubing with a 6” radius. Well, I did and they want $500 for 4 bends. Now I know why most chassis builders use larger diameter and thicker tubing… they can make the bends on a manual bender.
I need a wider shoulder hoop than what’s available (Mark Williams, The Chassis Shop) because I’m 6’5”. What I’d like to find out if I can use a 2” spacer to widen the shoulder hoop with an interior sleeve. It needs to meet the SFI Spec 2.6A (7.50 Seconds & Slower). They allow for a single butt weld splice in the center of the upper frame rail, I just wonder if this is legal as well.
Thanks,
Andrew
