Removing rear window regulator assy. Help!

[Bernie Benz]

Apparently the “tab“ attaching the cable to the “lifter pivot“ (the part that slides up and down the guide rail) moving the glass via a pivot pin thru the plastic glass attached bottom piece, is broken.

Further, apparently this lifter pivot pin has an E-ring keeping it in the glass plastic piece. If so,(?) visible only with a small inspection mirror, how does one remove the ring to free the regulator assy from the glass? No mention in Bentley! Please tell me that there is no retaining ring on the pin!

Thanks guys!
