Replacement manifold stud
Does anyone have a link or part number for OEM replacement exhaust manifold studs? Manifold studs, not header bolts. Checked all my local parts stores and no luck. I found some in the help section but they were the wrong length.

Re: Replacement manifold stud
Every parts store has them; even AutoZone, Advance, Pep Boys, etc.
At AZ and such they are hanging on a card in the Help! (Dorman) aisle. They even come with the nice brass nuts so they don't rust all up again.
Pack of them at AZ costs about the same as the above but doesn't require you to pay shipping.

I saw them listed on Rock Auto, but was confused to see them listed as 10mm and thought I was looking at the wrong ones.

Any reason not to upgrade to stainless steel threaded rod?

Update:
The correct part number is DOR3401. The link to RA above is for the manifold to y-pipe connection.
