Passenger window lifter

When passenger window is lowered, the rear of the window does not lower at the same rate as the front of the window. If pressed down by hand while cranking, the window will lower. Window lifts without any issue. Hear grinding sound while lifting window.

Removed passenger door panel, examined window crank mechanism, and determined that the "Lower glass channel, rear" (ALA5747) is rusted, and no longer clamped on to the glass, therefore the glass will not lower without additional assistance. Replacement part is about USD$50, will try to fabricate one first.

Also will need rubber strips, which were suppose to be on the channel, but missing.
