Are there any members that can help me with installing original rear window in a 1937 cabriolet. I understand that it has a zipper on each side and seven or eight twist and lock pins along the top. The twist and lock pins are attached to a steel plate . The steel plate is screwed to the top back half of the rear bow need the size of the steel plat a drawing or photos anything would help. I think the steel plate is about 40 x 2.50 not sure. Thankful for any help. Bob-37 cab
