Easier in Australia than the original. I used my last spare.
Almost certainly there is a Johnson alternative for any and every Oberdorfer but you'd need to know the impellor model number or at least the pump model.

Your IP Adress indicates Australia but I don't know where in Australia so cannot recommend a source.
ps - if for some reason you don't know the model number then do a drawing of what you have and post a photo.
