I'm trying to remove the brake drums from the rear of my 1960, I've removed the 4 hex bolts, I shouldn't have to remove the adjusting round headed slotted screws, but that dang thing won't budge. I've been smacking it with a hammer and am about to get out a torch but didn't know if anyone has a suggestion on how to get it off.

Probably hasn't been off the car since 1959.

Looks like this for reference:


1960 Morgan +4 4 seater
1997 Nissan 240sx S14
2011 Nissan 370Z
2009 Triumph Street Triple
