I have an 83 with a 12a. I am looking for a good resource for intake manifold bolts. One of the bolt holes had to be tapped, so that one is slightly larger than the rest. Does anyone have a good resource for buying bolts of the appropriate size and thread and material?

 

local hardware store should have what u need, provided u know the size and thread pitch of bolt needed.

 

Recommend a helicoil thread repair insert which will allow use of the original size fastener so all are same.

 

I just took one bolt to get the length and purchased some stainless steal recessed hex head bolts from Fastenal. At the time they would allow you to buy bolts by the piece but my local store now makes you buy the entire bag. Ace Hardware has them also.

 

tap it but use a standard tap not metric so it will be slightly larger the original
