Just doing some little stuff on the truck while waiting on the bed strips. The truck came with reproduction vent frame and glass and door window frame and glass but were clear glass. I wanted tinted glass so ordered the tinted glass and installed them while rebuilding the vent window assemblies that came with the truck.

I have a question on the forward door window post where the vent assembly sits there is a hole a little more than halfway up. I need to know what that is for. Here are some pics including one of the mystery hole. Steve
