Rather have clutch head screws than Philip. Have old original set of bits they fit tight, found cheap Chinese bits loose an was able to snap one. It appears that GM used them when they needed a heavy duty countersink bolt. They were still using them in 1962 maybe latter. Had to pull wiper motor, it used them.
Windows are all problematic from that era. Latches too. Im contemplating a conversion to electric, pt cruiser as a donor. Holee! You know its serious when you fire up the stick welder.
Great job at correcting GM’s “only” mistake.

Those are called clutch head screws.
A bit like my old Hyundai, go's down fine but got to pull it up! LOL. Bit hard to see it, isn't that called a 'one way' screw?
