My drivers side rear side glass is cracked on the inside and not on the outside as if it were double pane. I was wondering if I can steel just the glass out of my 86 and install it in the 1990? Would I have to remove the entire windowframe to do so or can this be done in the truck? seals and all that stuff is much better on the 90 and the frames on the 90 are silver which I like and on the 86 they are black...
