I have a 33 Dodge DP6 sedan. The windshield has the guide tracks with large thumb screws on both sides and I have loosened those. Before I just put more pressure on the windshield to open it, I wanted to make sure there was not a trick to opening these, or typical problems with rust or seized hinges, stuck window seals, etc. Any suggestions would be GREATLY appreciated! Thanks again, MoparBoy
