64 Dart Front Drum Removal (and more!)

Soon I will be replacing my 64 Dart's front brakes, drums and all.

I have opted not to do a disc conversion kit for three reasons:
1)Cost (Like I need another reason after that!)
2)Keeping the car as close to original as I can
3)I have never had any problem with stopping power whatsoever w/drums

I've never serviced the brakes on this car yet, but on my old 74 Dart Sport, the rear drum basically came right off once the tire/rim was removed. Are the front drums on the 64 really very different? Any tricks I will need to know?
I realize it may require relaxing the adjuster/star wheel mechanism, but besides that, anything I should know?

(It may be a few weeks before I do this job, as I may have to purchase the parts over a few pay periods. I intend to go all-out and do the bearings, seals, springs, whatever else, unless it's obviously not needed (The last owner was really good about maintenance!!)

Another question. I still have a single resevior master cylinder, and I am considering an upgrade to a double. Any problem with that on a car with front drums? I realize I will need a valve/splitter (at least I think I will!)

Fill me with knowledge!!
