Any like year power window motor will work Camry, supra, tercel, doesn't matter.
Regulator will have to come from a salvage yard.
4 bolts hold it in
Install without the motor attached
The regulator has to be in the proper configuration to accept the window track and the gears have to be meshed evenly so the arms raise and lower at the same level. This is trick cos one of them has a wound spring against it.
Further the arms have to be in a certain position for the whole operation to fit in the hole in the door skin.
There are two holes in the regulator body the correspond with holes in the regulator arms that (with a bolt installed) will loosely hold this mouse trap in the right position.
you slide all that in the door skin and with your 3rd and fourth arm you slide the window down the window hole and mate the two.
At this point resist the urge to loose a finger...
bolt it all up and notice that the left arm is 1 or 2 teeth off and start over...
This all came straight from Haynes,,,, Good luck. Dont give up.
