Get a piece of pipe or a long socket with a hole just larger then the head of the stud. Put that in back of the stud & set it on the bench. Have a helper hold the drum or prop it up with blocks. Get a heavy metal bar, an old shaft or something & put it on the stud & like the guys say, get mad at it. Don.t try to pound them out resting on the drum. It only soaks up the shock & can distort the drum. Going back nwith the new ones just reverse it supporting the face with a socket. Put a little grease on the new studs to help. That looks like a good drum. I dont see any reason you cant just replace the suds. If nessesary I believe we can come up with a replacement. I wonder if its the same as a 48 back car. John has several of those.
