Manifold collector bolts - part #'s??
I'm going to be replacing my y-pipe this weekend and am expecting to break one or more collector studs. I have searched this forum but cannot find a part number for replacements from HELP or anyone else. Does anyone know what I need to buy?

Actually, I did read that they are M10x1.5 studs, but I was hoping someone actually had a part number...

Get stainless bolts, and forget the studs. Thats what I did, and it worked great... they didn't even need WD40 to remove them!

The part # for motormite "HELP" studs is 03401, I found out today however, mine came off perfectly after 2 shots of PB Blaster and are even good enough to be reused!!!!! Thank *** I live in the south! The downside? The '86-'90 single 3" cat OEM replacement y-pipe I bought does not line up with my 305 TBI manifold outlets so I had to order some headers. I needed an excuse anyway!
