Any bolt or hardware store... or even Ebay, if you don't want to buy from Fiero Store. There is nothing special about the stud kit... standard items.

I just purchased stainless steel bolts and used them. They are still in place years later. Forgot the size but they may have been 8MM.

Stainless has 2 issues though.

Stainless has a grade strength of just under a 5 and the threads cold weld (aka: gall).

Also, most stainless hardware is constructed out of 18-8 which is resistant to corrosion but susceptible to it. 316 stainless is highly corrosion resistant and 410 is more in the lines of a Grade 8 but not as resistant to rust as 18-8.

I just used 8mm hex socket set screws from (good) hardware store - easy to install/remove w/hex key, and grade 8 plus.

Hi Mike,
Will those come out later? Seems like you would not be able to get them back out in a few years?

Fiero V6 Exhaust Manifold Stud Kit $15.00 plus $5.00 S&H

At this price, is it worth the risk versus pulling the whole motor later to drill out a bolt?
