3D model of a 1980-1996 Glass Sash Rear Window Regulator Guide Lower (GM 20085728).
This was modeled after a old part removed from a 1990 Buick LeSabre. If it's a little small, it's probably due to the original plastic part shrinkage. You can scale it up in your slicer if need be.
These are no longer available, if you print them, use a VERY durable filament. They are under ALOT of stress moving old stuck windows.
