That is a 33 rear end ,Not 32. You need to take the cover off of the differential and remove the spacer block and C-rings off the ends of axles, then you just pull the axles straight out and the drums are on them.
Thanks so much! Next question, how do I remove the drum from the axle for turning etc? Beginning to think there is more than a rear end that is 1933...
The wheel studs must be pressed out to remove the drum. The studs can not be reused. The drum can not be turned on a brake lathe because it is stamped steel and not cast iron. Also is very thin.
