P body wipers motors

It appears to be several different motors for the P-body over the years. I have a 87 motor and also several from 91+.
I would guess they should exchange as the mounting plate is the same and even the same electrical connector. The 91+ motor and gears are smaller in size. I tested both on my lab power supply and both draw similar current to each other. I estimate on the order 6 amps 12V. The 91+ I tested may turn slightly faster but I did not time.

Are the various P body wiper motors interchangeable?

In my experience swapping motors from car to car in emergencies, they'll all fit the bracket, but the connectors can be different from year to year. I've seen no ill effects on operation when swapping the different motors.

Thanks for confirming.
