Here's a tinted driver left side vent window assembly recently removed from a 1969 Skylark 4 door hardtop with a/c.The window frame shines nice and the glass is nice,there is some pitting on the chrome piece.This might fit other GM years makes and models but do your own checking.

Over all this is above average and good for a nice driver as is.Look at the pics closely because You get what's pictured.
