Refurbing rear 9" drums on my '72 Demon

Alright, here's the story. Replaced shoes, hardware/springs and wheel cylinders. Adjusted brakes to rub slightly when cars in neutral and bled brakes. When car is put into drive and brake is applied the driver side turns ever so slightly but the passenger spins freely (like car is going 15mph). If I try to adjust brake any more I cant get the drum to slide on. Driver side adjuster shows 5-6 thread, passenger is bottomed out maybe 1 thread.

Repair manual said stop light switch may be adjusted improperly which I know it is because it doesn't contact my brake pedal securely and I shimmed it to make sure my brake lights go off. Can't get to the screw to adjust it because of my fat knuckles. I don't know what impact this would have on my brakes though....
