I see the thread is titled semi Girling drums; do you have hydraulic brakes on your car? the hydraulic backplates, being as they were/are modified Morris Minor items are often not square to the brake drum -this doesn't seem to affect their effectiveness as the brake shoes self-align.
If the axle ends do happen to be out of line to the half shaft axis, the wheel bearing life will be very short (hundreds rather than thousands of miles) and the oil seals won't stop diff lubricant reaching your brake shoes. Welding the axle casing to attach spring hangars etc. on any live axle usually pulls the casing out of line. Even after machining axles cases and ends to shorten them it's not unusual to need to tweak the casing after welding as a result of weld distorting even when the parts have been jigged. I have straightened a lot of casings, A7 and others, the method is quite low tech....
