Window Rehab

[Bill <Y1TopBanana73@xxxxxxxxx>]

When I roll UP my pass side front door window in my Coronet, it makes
a lovely grinding sound @ the bottom end of it's travel, but it
doesn't do it when rolling the window down.

Any ideas what's going on in there? Are the parts / slides, etc
available anywhere to fix it" I have not torn it apart yet.

Thanks
