I tried the search on this site=no matches

Training for the Gr. TX Cat Race, my 2nd year to do it, off shore we broke the rear, port ,aft, inboard cross bar bolt. You know, the one that holds the strap bracket on the rear crossbar. It looks like a special bolt, my mechanic ground crew says it's zinc.

I've heard of a 6.0 in the Tybee 500 breaking some cross bar bolts also.

I'm just beginning my search, it happened yesterday. If you know first hand what I need, and if I should be replacing all of them, I'd appreciate it.

I have about 10 days to get them.

Thanks,
