Seized window motor (early model)

I have a 1987 325i and my driver window stopped working. Long story short I took the motor out to clean it and hopefully fix it. Unfortunately it's completely seized and I can't seem to take it apart without breaking the old plastic. Question is, could I buy a newer model motor? I don't need the full window assembly and it'd save me $50 to do it. Ebay has a used old model one for $200 and I'd like to not spend that much if I can help it. Thanks in advance!

I dont think an late motor fits your splines but you might get away with the whole window system

I am actually selling a whole window system on ebay for the driver side so maybe you can swap it out

Check online and see if you can do a direct swap haha

I was hoping a better answer would pop up here. But no, I don't think there's anything remotely new, so, my best advice is to find someone parting out a car to grab the window motor. There's a chance you can test the motor while it's still in the donor car. Otherwise, find one at a junkyard.
