In my 65 Cuda, Both wiper pivots are easy to get at even without pulling the dash gauge panel... I also do not have A/C... Fact is I don't even have a heater...
I did remove my drivers side bucket seat so I could lay on the floor for the left side pivot... and other then that, nuts came right off the pivot studs just fine.
Just my Two Cents... But, remember, my cuda has been an ARIZONA car all it's life, so no corrosion !!! :D
