I need at least two exhaust studs for my bus. On one the nut was fused to the stud and I can't get it removed. On the other, apparently I didn't torque it down enough and it rattled loose and fell out.
I have new copper nuts and now I just need the studs. I have only found them from German Supply and with shipping from Canada, two studs would cost me about $40. I can't find a source for them anywhere else.
