LSA Manifold to Cat Pipe Stud and Nut Size What size are the studs and nuts for a LSA exhaust manifold to cat extension pipe?
I have the studs and they seem to be M10, but they are not 1.5 pitch (nothing SAE is even close). They seem to be slightly larger, but they are not 1.75 either. a M10 x 1.5 nut will only make a few turns and a M10 x 1.5 die isn't going to work either.
Any info or part numbers would be appreciated. Thanks!

For some reason all 4 studs that came with my manifolds were messed up. Fortunately the threads in the manifolds themselves are fine and they are definitely M10 x 1.5
The Studs are GM Part # 11589264 and they are M10 x 1.5 x 30/M10 x 1.5 x 16.
The nuts are GM Part # 11517996 M10 x 1.5.
