Metal sail panels 72 to 73

Lets set the record straight.
the 73+ glass has to go with the 73+ frame and latch, My glass looked like crap so I got a pair of wing windows that were 70-72 complete and they just slip right in the opening. The 73+ sail panels are plastic, no so for the 70-72 which are metal. everything was fine until I installed the rear bucket seats, now I have to trim down the length of the handles about an inch to clear the seats.
