What are the approximate deminsions of the big back window and small back windows for the truck? Mine looks big and then it looks small. If any one could point me to the measurements I'll know what gasket to order. Thanks! Klf
a big back window will take up pretty much the hole back of the cab above the bed. a small back window will only take up a small amount of space in the senter of your cab above your bed. hope that helps cowboy 1961 chevy 1/2 ton shortstep known as sarah(496 big block coming soon)
