Great score!!
Wow, Eddie, you hit the mother lode of GE Mobile Maid parts there! Looks like you could rebuild three machines!!
I am not sure that the motor and pump you found are going to be direct replacements BUT you could probably fit the '57 impeller and drain chamber onto the new motor.. Not that I've ever done that, but it should be possible!
Where on earth did you find this gold mine of parts and did they have any thermostats for a 56 GE washer/dryer combo? lol
