    Anyone know where to get them? I took my stud to ace and it fits a 7/16 thread but when I go to stick a 7/16 bolt in it it's a no go. The studs came out when removing the pipe and the bolts got slightly rounded so I have no interest in using the factory studs

    It shouldn’t be standard threads at all. Should be a M10 X 1.50 and you need to measure what you have for length.

    Thank you. I'll double check the length it was 40 or 50mm. Also it's not a factory nut that's for sure. Driver side was 18mm these are 16m.

    Ok so after investigation I figured out the studs that came out are a 7/16. Now obviously the right thing to do is take the manifold off, drill, tap etc.. not worth it.

    My idea is to put a 7/16 stud back in it with jb weld on the treads to make sure it holds. New nuts and call it good. Fishing though what size studs actually fit each hole is a pain. I've tried standard and metric. Threads on each side are different as well but the 7/16 does get tight once it seats. So I'm thinking the jb weld holds it.

    Drill a hole through and use stainless bolts and nuts

    Cant get a drill in there with the tight clearance. If I could I'd just tap new threads.
