1988 Drivers Side Window Falls

The driver's side window in my 88 245 has decided it won't stay up.
It's a manual system. The crank mechanism withing the door appears
worn, and the curved, toothed piece keeps falling out of the mechanism.
As long as I don't touch the crank, it stays up. What is the name of
the part I need to search for to do the repair?

Thanks!

John

Sounds like a window regulator.

Find a replacement at a junkyard.

It all unbolts without too much drama.
