How da hell do you pull off the hub from drum!

Unless your replacing the fropnt drum with one that didnt come with the hub, there isnt any reason to remove the drum from the hub. To remove the drum just to do the brakes you remove the center bearing dust cap, pin, cage and unscew the nut.

This sounds obvious to most but I could understand not knowing how to remove the drum IF you have never worked on front drum brakes before. You should REALLY get a repair manual for your make and model OR at least a haynes manual covering 1960something and up rear wheel drive mopars. From the late 60's to the late 70's BASIC technology of our cars really didnt change too much.

You should be able to get to the front shoes in less then 10 minutes without hammering anything
