1969 Power windows...

Operation power windows; Grrrrr, learning curve.
Ok, starting to mess around with the power windows.. I am looking to use the new motor. It works fine.. But when I install the gear and pinion, it locks up and doesn't move. I believe the gear and pinion is a multi-piece unit? It will spin freely on the rotation shaft, but when I push it down to engage the worm gear, it won't move. I have a steep learning curve on this I am sure.

Aftermkt motors or gears ?

I am thinking, as much of a purist I am, to get new motors.. I'll have the original ones.. Just done fighting them, 50 year old motors...
