How do you remove !@#^%$ rear hubs

["Kentech MotorSports" <kentech@midmaine.com>]

I decided to swap guts from one rear axle to another since I've got good
guts in one and a good housing in another. May be ending up as a bad
decision but .
 
1967 TR4A solid axle -
 
1)       How to you remove the blaster rear hubs. I need them off to put
in new studs and change the seals & bearings. 
2)       What's the best method to remove the studs - grind off the
backs then unscrew with two wheel nuts? One stud hole (at least) is
stripped so I assume a machine can fix it and set a new stud OK. Right?
 
Thanks in advance for any help.
