I feel the rear glass on a tri five chev 2 door post is too large. I think the 55 &56 ford two door post has better lines with regard to the rear side glass. I was thinking on converting my 56 chev 4 door to a two door. And building the front doors out of two spliced together 4 door halves. and making them about two inches longer. thus reducing the side window and using wagon rear door parts to fill the gap and not have the dip in the window opening.
