I believe they are interchangeable. I have a 1977 . Getting very wet this year , even in sunny California. marc -209-969-2413
I've only had this truck since 1977. But I just start it and go. Beyond that I really don't know that much about it. Thanks for the headsup. Like to find the jerk who busted that window out.
I "can" get a window from a local yard out by me. they have two 77s. i think they're still there. i'm not sure how i'd ship it and all that. i took out the backglass of the same truck i'd be getting it from. lmk.
