I've put the newer vent glasses in the older trucks with no problems. There are 2 screws in the forward jamb on the older vents, where there is only 1 in the newer ones, but it's a running change somewhere around '88-89 or so. I like to look for the newer vent glasses in the pick- a-parts because the rubber is usually inbetter shape. I hate rebuilding vent window assemblies. The shape of the glass is different, but the assemblies will physically interchange. The ones in my '74 right now came out of an '87.
