Exhaust manifold to cross over pipe flange bolts?

[darkred87T]

Does anyone know the exact size or a good place where I can get them? I guess I can try Lowes or something but are there bolts I can use that will stand up to the heat?

your local GM dealer?
junkyard?
Help section of your favorite auto parts store?

They are 10mm x1.50 thread pitch. Stainless is prefered.

Help section has studs. Thats what I use all the time.

Thanks for the replies. I never thought of the Help section. I'll check it out.

Some 86's have M8X1.25. Mine does anyway. Damn near impossible to get the crossover to seal when you can't torque them down and you have to use washers so they dont pull through the flange on an aftermarket crossover pipe. There's even a footnote in the 44W Parts Catalog when you look up a replacement crossover pipe.

I probably need a new x-over pipe too becuase the threads stripped out of the one flange. I'm using a nut at the ned of the bolt to secure it.
Between that and all the patch welding I had done on the manifolds over time the whole thing is a big mess. Maybe it's time to get some headers. I hear those "made in China" ones are a real bang for the buck.
