The driver's window in my 940 would clunk loudly when it went up and it wouldn't go up the entire way. I bought a salvaged regulator/motor assembly.

Now that I'm putting the new one in, I can't get the 4 rivet holes to line up. The two regulators have the same part number. The old one has a big coiled spring on it at what I would consider the main pivot point. This is not on the replacement. Also, the old one has a chunk of metal missing in the same area. I assume this is where my problem was.

I removed and replaced the motor in order to get the new one in the same position as the old.

From the FAQ:

[Response: Sven/Darius] To get the whole thing out, first take the door trim off. Then raise the window to full upright position and secure it there. Unclip the three clips that hold the regulator scissor arms in place. Pop the two bottom regulator retainers out of the plastic sliders that are mounted in the bottom of the window metal strip. You'll break the top lip of the retainer but it will be ok. Unbolt the three or four bolts holding the motor/regulator in place. If you have rivets, drill them out with a 5/32 inch drill bit. With a little cursing and wrestling, the whole thing comes out through the big lower opening. Remove the old motor, bolt it onto the new regulator, reinstall. All should be well without having to remove the window. If you have to remove the window,it is held on to the scissor-like appendage by two clips, facing the outside of the car. Angle it slightly to remove.

From above:

Unclip the three clips that hold the regulator scissor arms in place.

What are these clips?

Does anyone have any idea what I'm missing?

The two rear rivet holes are off by about 1/4" or so.

Thanks for any insight.
