Quick update, or really there isn't an update. I have yet to get the pins out. After soaking for weeks with PB Blaster I couldn't get them to budge. So I figured I would drill them. After flattening 2 center punches, I have yet to make a dent in those pins with my 7/16 cobalt drill bits with pilot tips. I even tried starting a pilot hole with a smaller bit and got nowhere. I figure at this point I am left with using a torch to heat up the brackets hopefully enough that I can then pound the pins out. I know it will trash the paint but I can fix that later. 20 years of hardened pins pressed in are a major pain. Any other suggestions?
Taking the brackets completely off the body is not an option as the nuts on the backside under the dash will just spin and I cant get a wrench back there to hold them without first removing the cage and then the dash.
