So I started my header install this morning. The exhaust manifold studs were in such bad shape, I've had to fight with every copper nut I have pulled off.

Now I managed to pull a stud out. Anyone that's done this recently have the OEM part numbers for the manifold studs?

I figure it probably best to replace them all instead of trying to put new nuts on such corroded threads and fighting it. It looks to be a 5mm size on the end for installing them.

Also by any chance, anyone got any advice on the two bottom nuts of the stock manifold closest to the firewall? You can hardly get your hands back there, and from the bottom it also looks sketchy like I may have to try a few flexible adapters in-line with extensions to reach them. Every other nut I've been able to get from the top.

This has been one of the bigger PITA removals I've been through, and I've done tons of headers in the past on various cars.

Thanks!
