Default Exhaust manifold bolts...

Any alternatives out there....other than used originals or hardware store bolts?

I know I bought new ones from GM about 15 years ago....but not optimistic on current availability..

If you don't need the various studs included on the OEM bolts then try some place like McMaster-Carr where you can find the exact sizes you need and a choice different strength grades and materials.

Or AMK might sell them very close to original style ... I think there minimum order is $50.

Also our host Ames ... says it has the correct bolt set.
