Ok, here's my .02

Order enough of the complete paddles to replace the ones you want. And a couple of just seals for grins. It's a pain to get a new seal into the paddle, and you run a chance of distorting the metal frame internal to the seal when installing it in the paddle.

On my air op dump valve, the paddle stem pulled out of the paddle. Uh oh. I threaded a long skinny lag bolt into the remains of the paddle to get it out. Used a mighty crude technique of heating the lag with a torch, threading it until it stopped into the plastic, withdraw and repeat till I got about an inch of it threaded. Grabbed the bolt just below the head with trusty vise grips. Then used a pry bar to unstick the paddle.
