The '67-72 trucks weren't meant to have one-piece side windows. Therefore, in order to make the windows work, a triangular spacer needs to be installed (like late-model Chevy trucks) in the front lower corner of the doorframe. On Shorty I used a Brothers Trucks window kit. They provide their own spacer. However, considering that the top is altered on my truck, I needed to create a spacer to fit the profile of my window frame. Last month I made the template, and this month I am making the spacers needed. My first step is to trace the pattern to a 16-gauge piece of sheetmetal.
