Default Anyone know offhand what size the "turbo to manifold" studs are?

I'm looking for an extended set to use a T3 adapter on my 90+ manifold. Is it m8 or m10? 1.25 or 1.5. I'm getting conflicting "internets reports!" lol. Are they the same studs as the exh mani itself? Thanks for any insight.

Original ones on a 90+ are m8, same threads as the manifold to head studs, but I couldn't tell you the pitch off the top of my head

Thanks guys, I appreciate it. I almost got them (m10/150s) from a Diesel website. Figured they were bigger? hard to tell for me without taking my turbo blanket off, etc. Now hopefully they have extended versions?
