Hey--I have searched on this topic, but still can't find the answers I need. Hopefully somebody can point me in the right direction...

I have an '84 300SD (W126). Window in question is rear driver side. Got the panel and plastic off ok. It's clear where the regulator (White plastic piece) has broken in two.

I see it slides out of the rail and the new one slides in--no problem.

Here's my dilemma(s):

1. There is a rivet at the end of the arm that does the lifting. How do I get attach this rivet to the regulator?

2. Do I need to remove the motor from the window to work on this? Someone told me I need to, but am unsure.

3. Does the motor just unplug?

Thanks in advance!

Bud
