I'm pretty much using your build as a mentorship exercise for mine. I had hoped to put a full cage in mine that complied with NHRA rulebook-but I've scrapped that because it will pretty much require permanently attaching the body to the frame thru the roll bar mounting to the frame. Soo, I'm planning to copy your seatbelt bar welded to the sub rails, with minor modifications. If I start a build thread, I hope you will subscribe as an advisor. I've been a car guy my whole life, but have always farmed my car out for stuff that required tradesman skills. I just ordered a Millermatic 211, and will pick up my tank on Thursday.
