Y pipe Broken Stud? I've searched, searched, then searched some more for the GM part number for the exhaust stud that connections the Catalytic Convertor to Y pipe but have came up with only part numbers for the manifold studs. Does anyone have a clue what the part number is for the stud and nut that connects the Y-pipe? If so I'd truly appreciate it. Thanks!
I'd just drill the hole out a little bigger where the stud threads in and go buy a bolt, nut, 2 washers, and a lock washer and it's fixed. Just make sure to put some anti-seize on the bolt threads before putting the nut on.

Actually that's how it's rigged up right now just have a bolt in place of the stud. I'm just a freak about repairing things back to look like factory, I drilled the stud out and the thread ended up coming out fine so I figured I'd put the factory stud back in if it's possible to get one.
Try going to the parts counter at a local gm dealer, they can look it up.
That's what I do when I can't find the part # online.
If you end up leaving that bolt on long term I'd get some anti-seize, remove the bolt and coat the threads good, then re-install it. That way the threads shouldn't rust out.

Already tried that one at two local GM dealerships the studs are sold with the catalytic convertor cannot buy them separate. 
if you ask me, but I was hoping maybe there is a certain part number that's out there of the studs, that the parts diagram isn't showing.

If you can figure out the stud length, metric or standard, and size you can get a new stud to replace the broken gm one.
