frozen nuts

[Jeff <jefflee77@earthlink.net>]

Hey list!

I've got some "frozen nuts" on my exhaust pipe/manifold  I'm having to resort 
to a machine shop to bore out the studs. I need to let them know what size 
thread the new studs have.  I plan on ordering pipe, studs and nuts from Moss, 
but thought someone might want to dazzle the rest of us with thier knowledge.
