Hi Peter, I have a couple that only turn in one direction & I also have at least one '59-60 that needs help. If you can resurrect the '62 motors, then you should be able to fix the '59-60 motors. I believe they are all the same basically except they're inside different outer casings.
I'd be happy to give you the '62 motors for fixing the '59-60 motor(s).
What do you think? There will be shipping costs depending upon how many are shipped...weight/etc. which needs to be negotiated.
Cheers,
Gary
