I have two good original GM read side windows (the FIXED kind with the rubber seal all the way around, "business coupe") from a 1952 Chevrolet business coupe. (150 coupe? Styleline Special Sport Coupe? I'm not clear on the model names for these cars. All I know is they never slid like in my '51 Deluxe coupe. They mount into the car body with the rubber gasket and don't move.) Original rubber is intact but stiff and cracking. Window glass is NOT cracked and very little fogging. $20 or best offer. Will deliver to the Stray Kat 500 show in Dewey, Oklahoma in May 2019 OR the HAMB Drags in Joplin, MO in August. I am willing to ship them at your cost.
