Hey, I'm new here so I apologize if this has been addressed already and I did not see it. I just picked up a 1964 Mercury Park Lane 4 door hardtop breezeway, and I am shocked how little information and/or parts are available. It's in amazing original working order with the exception of a missing (previous owner lost it) left side passenger power window motor. I've spent weeks looking for one, but am at the point that I just need to replace it with anything that is compatible. Any ideas? Not one clear answer on if that is also an option or not. Thanks in advance!
