Im having a hard time getting the pitman arm off of my 68. The box is numbered 5691676, which I believe is a Saginaw box?? The arm is the type with the joint mounted in it and I just wanted to get it off so I could bead-blast and recoat it while I have everything disassembled. I havent tried heating it up cuz I wasnt sure if Id damage anything or if itd even help. Any help would be greatly appreciated. Thanks, Charlie
