52 Carl

I have replaced the side windows on a 51 with new glass. Seems to be the same thickness as the old glass. The old felt runners were really bad so I also replaced the felt runner in the division bar that runs the entire depth of the door. Have done this three times with different parts from different vendors. They all seem to be too small. Very tight on the glass. As you know getting the vent window assy in with the glass rolled down is a bear. I have gotten the vent window assy to mount properly with all the screws etc and the external rubber correct but I have not had any luck with any of the felts used. They all seem too tight. Very tight to roll up and down. Tried them on the bench and can hardly slide the glass thru them. Any tricks to this...
