You have the glass out of the 70's model or the 91 thur 93 model , they might be the same cut for all the years but I am not sure . I need to know where I can get the window gaskets for the 70's model from then I can see if the 91 thur 93 glass will work. I saw a 78 club cab the other day that a small car lot in town just got from ebay for a keeper and the glass hole looks to be the same but I am not sure if it is .
