Air Injection Pipe Bolts
I have a 1984 Bronco wit 351W. It has a bad exhaust leak and I was getting ready to change the exhaust manifold gaskets when I noticed the Air Injection Pipe was no longer connected to the block. Since I live in Cali removing the smog equipment is not an option.
What size bolts hold the crossover pipe on? Searched all around and can't find the bolt size.
Thanks.
