Hi guys! I am new but need some help. I have a 65 Polara hard top and would like to chop it 4 inches. I was told that if I sink the windshield and back window into the cowel and deck lid the do not have to be cut? I have chop the top on my 49 Merc but I dont think I can tilt the back window and still have the quarter glass window line up and still go up and down? Any suggestions or advice will be a great help.
