Have the doors off my 66 GTO in preparation for media blasting entire car soon. Want to remove hinges. Bottom one is no problem since it is attached with hex head bolts. Top hinge is attached with 3 Phillips head screws that I have not been able to break loose. Soaked them well with WD 40 and used an impact driver with a large hardened phillips boy but no dice so far. Before I continue banging on them with this tool thought I’d ask for tips from others who have already found a solution.
