Default Power window motor replacement....

Getting ready to change out the PW motor on my 94 Z, driver's side.
I have been doing a search and trying to read everything I could.
Already have the door panel off, getting ready to take out the metal plate. Also have the replacement motor ready to install.
Just wondering if anyone has anymore tips that will help me out. The motor has replacement screws and nuts in place of rivets. And what is the best way to secure the regulator when taking out the old motor.
Any info is appreciated......thanks.....Tom

Thanks for the reply.... my nuts are already locktight (sorry couldn't pass that up)
So you are meaning to put a zip tie around the regulator before motor removal to keep it in its place? Am I understanding this correctly?
Thanks for the tip(s), appreciated......Tom

I feel like Tom's Garage with both the 82 & 94 getting repaired....
Of course snags around every corner.....:censored:....
On the 94 door panel is off, metal plate with door lock actuator attached, removed....inside of door looks great as you will notice with the pics enclosed.....LS door guide looks good, nothing like when I replaced the one on the RS, so I will leave that alone. Probably will change out the PDL actuator, simply because I am in there and have heard some type of buzzing from time to time, especially when I close the door.
Ok, so I'm all excited, since I ran into a major snag with the 82 LS TA, but that's another story. So I get my replacement PW motor and am going to try to test the new motor...Well guess what, comes with 3, yes 3 adapters and not one fits the plug for the wiring harness. :censored: I am not going to cut and make one that works, I just want the correct adapter (pigtail) that fits....
So if anyone knows of a certain brand motor that comes with the correct plug-in, kindly let me know, so I can purchase that brand and send this one back. Also been trying to find the harness clips that go through the water barrier and into the metal plate, I did not break any, but would like to get some spares, so if you know where to purchase, it would be appreciated.
At least this week the weather will be nice enough to drive with the window down, and cover the Z at work.....as they say sh** happens.......thx.....Tom

Your original window motor may be riveted on. You will have to drill them out. Your new screws will replace the rivets. Have fun, been there done that.

I went from the old style to the new ones on my '87 so all I can add is to make sure you mark the position of the mounting bolts for the regulator and the window studs, then you won't have to worry about adjusting the window so it closes properly.

Yes, the new motor does come with the screw set, I imagine strong plastic ties will keep the regulator in place during removal....
