Does anyone know if the 2 pieces 1/4 by 1/2in. with 4 holes that join the two windshield frames are the same angle as the cab or are they slightly more angled so as to place additional pressure on the outside ends of the frame. I cut these out of the frame to get the two halves apart; because they were rusted into the frame. I made new ones from aluminum but I might remake them from brass. The steel piece I copied had an angle which is more than the cab angle. The little "T" shaped sheet metal pieces are the same angle as the cab. Thanks.
