Re: !956 Power window electric motor

As mentioned, picked up a Dorman motor and have been playing around to see what could be done. Here are a few photos of the idea.
First photo is a stock motor and another with the pinion removed. The pinion is only held by a single clip.
Second photo is a stock regulator with Delco motor removed. The original motor retaining plate and rubber gaskets are reused and an adapter plate is screwed to the regulator using new screws.
Third photo is the adapter slid over the motor pinion support with square adapter end fitting the receiving portion of main worm gear.
Fourth photo is new motor installed and another view showing the new adapter in position between motor and regulator side. With the adapter inserted into existing bearing support on regulator and being supported by new motor and completely keyed into worm gear on the other end there should be no need for any securing hardware.
Fifth photo is another view of motor installed and the direction control relays that would be needed.
Sixth photo is of the parts: Mounting plate, adapter, motor and the square washer off the original pinion would be reused as a dust seal.
I did make a crude zinc casting just to prove the motor could do the job. The permanent magnet motor is surprisingly strong for its size and had no problem moving the bare regulator against the spring, With a window to balance the spring it should be strong enough to work in the car but the adapter will definitely have to be of stronger metal than zinc. Will be sending the assy down to Riki next week so he can look it over and see what can be done about making a proper adapter and mounting plate. If that works out he will install in one of his doors to see if it really works.
