Mounting Front Window Motor
 

Just a quick question concerning mounting. I had a rf window that was broken. the motor woudnt go either direction. Pulled the old out and the regulator and motor. Cleaned everything and noticed that the lash screw was turned in tight on the worm of the motor.Backed it out approx 1/4 turn and it worked great.tested it on door and everything was great.when i had it out,I noticed that it had 1 plastic doughnut on 1 of the mounting bosses.Im sure these are for rattle secure mounting of the motor on the door.My question is what are they called and does anyone have a part #.I do already have them ordered frm my ind mercedes shop but he never did tell me a part # or the correct nomenclature.Id just like to make sure i ordered the correct part. cant believe idiots got ahold of this car and actually lost parts.
