on most cars with roll out windows or deep revelles we use a piece of 3/8 or 1/2 aluminum sq tube to make a spacer. hide it inside with a piece of door panel wrapped with fabric. i've done a bunch of them on 35-40 fords. set the glass in the butle rope and install s10 trim. DO NOT use any silicone to set the trim. wont hold. i use window urathane sealant around the edge to set the trim. let me know if i can help.
