Thanks! The hacksaw didn't even make a dent in the shaft, but the Dremel with "large" cut off wheel was able to get inside the cages and make a couple angle cuts (like a V).
A socket in the vise and punch to tap the shaft through got them out in no time. Tomorrow I will fit the new motor into place (cages went onto new motor fine; in same orientation as the old one).
Yup, I took the entire drivetrain out of a 1980 International Scout II and swapped it onto a 1988 Wrangler frame and tub (YJ) and used a CJ nose. From 1977-1980 the Scouts had an optional Nissan 6-cyl engine, with it's T-19 trans, and D300 T-case. I used the D44 Scout axles too.
It took me about 11 months working on it on and off.
