Electric Window Motor Upgrade

If you get the right motors it is literally a simple bolt in replacement. No modifications whatsoever required. Just put a couple spade lugs on the wires from the motors and plug the car's harness into them. My 73 car had two wires, as do the motors. Even the wire colors match. Make sure the bolts aren't too long (all three holes match perfectly BTW). Rarely does a modification work this well with so little effort. To see why it works, time the RPMs on the old and new motors below:

Old:
New:

BTW, be sure that your regulators are clean and properly greased or your new motors will just be fighting the old caked-on crud. See what I mean here:

you want the rear.
i can take a pic if needed
you have to mount the motor after the window frame and
crank is in, because it wont fit as a unit
you need to use short bolts
heres my fronts
it seems it was fairly straight forward.
At the top bolt, i bent the frame out a bit at the hole on one side
that must be the early style,
the 74 crank system seems to be much easier

Hello, Thanks for the picture and information. My car is a 74, therefore I think that it should be easier. I will update all once I have done the upgrade. Regards
