I have a 65 F250 2 wheel drive pickup and I have been doing a lot of work on it. I just got done removing all of the rust from the front clip and repairing the radiator support. While I was in there I replaced the freeze plugs on my 352. When I replaced those I took the exhaust manifolds off. The drivers side has a heat riser that didn't work. I took the flapper out. I am now trying to put the drivers side exhaust manifold back on and have an issue with one of the studs. The studs are longer because of that heat riser and I cannot find anywhere another stud. I believe my other option is to get another passenger side exhaust manifold and put it on and extend the pipe. I would really prefer to get another stud. I have been to Napa, O Rileys, Autozone. I think this a 7/16 thread size and its about 3 3/4 inches long. Does anyone have any ideas where I can get a another exhaust manifold stud? Thanks

 

You could get a long grade 8, 7/16 bolt and cut the head off of it, keeping only the threaded portion.

 

That is a great idea. I am glad you pointed that out me. I should have thought of that but didn't. Thanks.

 

Do yourself or the 'next guy' and a favor and apply antiseize to all the hardware.
