Howard: I made no modifications to the pinion shaft. It is exactly as it came out of the original motor. I am a little concerned about that urethane piece also but it is not like this car will be driven daily. I am counting on it holding up in the time that I own it.
Mounting the Dorman motor to the regulator.
The 3 holes indicated, in SideTwo.jpg, need to be drilled out to ¼”.
I purchased a length of ¼ all-thread and cut 3 pieces about 3 ¼”. FYI, if you cut the all-thread at 3 ½” it may not go into the opening in the door. I also purchased (from Mcmaster and Carr) some 1 ½” long nuts
You can see in the pictures how I assembled the all-thread and the long nuts. You may need to add a washer or two on top of the long nuts. For some reason, I needed washers for this one in the pictures but did not need them in the first unit that I assembled.
My biggest concern throughout the whole process was the height of this modification. Laying flat on a table, the original motor and regulator are about 3 ¾” tall. The mod described here is 5” tall.
Having said that, it still fits into the door and does not appear to interfere with any other door components. The door is narrower at the opening but gets wider as you move it upwards. There is still about an inch or more of play between the motor and the sheet metal of the door when it's bolted in place.
This concludes my explanation of my PW mod. Fill free to ask questions or show me my mistakes.
