I'll be willing to bet if you call TTI and ask about the bolts, they'll just throw some in the mail for nothing, usually first class too. Those guys are good.
I'll have to check into that. For the time being I think I just got some at the local hardware store. Partially my fault as I didn't double check them after a few heat cycles, but it's all good, the headers are still attached, lol. Definitely need the small headed bolts in a few spots though, it gets tight in there.
