w124 drivers door window regulator problem

[JEdwards]

Car: 1987 300E w124

Problem: window started making noise (driver's door) when it was about 1/2" from the top. Pulled the door panel off and the last 2 teeth on the window regulator were ground down to almost nothing. I have sourced a replacement in a junkyard and will be going tomorrow to take it out. However, I read the manual on the MB service CD to take it out and it talks about "microencapsulated" screws and them needing to be replaced. Is there any information on this, because I have no idea what the hell that means?

Also, as far as removing the drivers side window regulator, what am I going to be dealing with as far as taking it out of the junked car (mention was made in other posts about putting the window down, an option I don't have with this car)?

Thanks for your help.
