[s-cars] Turbo to Exhaust manifold studs

[manuelsanchez at starpower.net]

Cody,

Do you think that the type of stud with the small section of threadless shoulder can be installed into the manifold with the turbo still mounted?

Thanks for the info.

Regards,

Manny

I just don't know if it's the correct stud length, but I am unable to thread it enough, or if I have it threaded in all the way but it's overall length is too long. I don't want to cut it for fear that if it is the correct overall length then I've boogered the only spare I have.
