I need to know what the thread size and length is for a bolt that couples the exhaust manifolds to the y-pipe.

I had to cut the originals up as they were rusted in place during tear down. and they have been long thrown away.
nothing in my stock fits, so I have to go buy new ones.

help, please?

I thought those were 8MM x 1.25 pitch x 25MM long.

Let's see if someone else can chime in here and confirm that my memory is still good.

I thought they were 8x1.25mm thread too but my manifolds thread seem a bit more course. like 8x1mm.

I thought length was anywhere from 30-40mm.

Im not talking about the exhaust manifold bolts that bolt it to the block, but the ones that bolt the y/crossover pipe to the manifolds.

thanks.

The P22 says they are M8 X 1.25 X 50 (10.9)

The Fiero store carry them if you don't want to guess and wait

they are indeed 8mx1.25. not sure of length, i just eye balled them to find the right size with a old one that was still good
