Convertor question
Tried to take my convertor off yesterday, but the bolts were just too rusted on. Spryed with penetrant, used impact gun, even heated them up a little, and still nada. I'm thinking of just cutting the bolt heads off and going that route, but how would I be able to get to the top bolts going into the convertor on the side closest to the engine bay? They seem so far up there that I can't even get a ratchet on it....

It is not difficult to pull the whole exhaust system on an 85. About all there is is the manifold bolts and air tube to the cat. That would remove the fire danger and give you access to use a breaker bar.

Mine was also stuck on but with a swivel head I was able to get a socket on and turn until the head of bolt broke off. Did the same on the other side, then it came right off. May have been luck but it worked!

Can't go this route because mechanics here in ny need to put a cat converter back on when taking one off..
