Have a broken manifold stud on my TB, checked it a while ago, it's broken off flush with the outside edge of the manifold. Because it seems like these things have problems with exhaust manifolds cracking, I'm just going to replace the whole manifold when I do the studs...

My question is this... Does anyone know if ARP makes manifold studs for the 4.2? I looked on their website and didn't see it, but that doesn't mean they don't carry it. Or should regular Dorman/Motormite OEM replacement studs be fine?

Has anybody had issues with aftermarket studs breaking, or is it just the OE studs and manifold?
