Question Oberdorfer Seals Removal Help

Hello All. I pulled my water pump to rebuild it (all impeller vames present and accounted for, sir!) and good thing I did because the shaft is very scored and the shoe is about half the man it used to be. I'm using the MMI rebuild kit for the Oberdorfer pump and it's brilliant. But here's where I'm hung up. I can't get those original old seals out! They're the bronze ones with the springs inside and those suckers are in there. I've tried prying out and I've tried beating out with a hammer and screwdriver tip alternating on either inside edge of the inside of the seal and I'm doing a real good job of chewing it all up (NOT the walls of the pump body) but not such a good job at getting the seal out. And that's the easy outer one.

Does anybody have a good trick or a tried and true method for getting these old metal seals out?
