Hello all,
I need to remove the exhaust pipe mounting bolts from my exhaust manifold on my 235. Is their a secret trick? It’s a stock manifold and it looks like they are threaded all the way through the flange.

When I got the truck one of them was broken half off and it had a vice grip with some good old bailing wire wrapped around it in order to form a clamp.

If I cant get them out I was planning on grinding it flat and drilling out the holes so I could jut run bolts through it. I have a Mil at work to do the drilling.
