Well, today I tried to take my cab mounts off. No problem with nuts or the bottom mounts. Now the best part. The upper mounts are stuck to the frame. I tried for over 2 hours to get them to free and no luck. I don't have an air chisel or I would have used it. I have tried

all kinds of things and no luck, so now I'm at a standstill. Help!!!!!. I've should have used some of my left over fire works.
