The door panels are universal for all window and lock combinations. This truck is equipped with power windows; therefore, the inner measurements of the window switch is transferred to the panel, and then 1/4-inch holes are drilled just inside the corners of the measurements. Next, a cut-off wheel (a small hacksaw blade would work as well) is used to cut from the top of each hole to its corresponding hole. Continue this until the square hole is cut out. Duplicate this process for door lock switches. In cases where manual windows are being used, use a hole saw to cut out the necessary area.
