Stock Exhaust Manifold/Turbo

Location:

Exhaust manifold to turbo flange nuts.

The two closest to the firewall apparently got loose and fell out. They even had the tabs to prevent the nuts from falling out. So much help they were... Anyways does anyone know the specs for the nuts? I don't have much room to measure the threads. Any suggestions on keeping it threaded? Will lock-tite just melt from the extreme heat? Will I be able to tig weld it with the little clearance I have from the firewall to the turbo? Thanks.

I don't know the thread off the top of my head, but you should be able to at least MIG the nuts in place...just a spot, nothing crazy.

Stainless lock nuts have always worked for me. Even with a dab of antisieze
