this weekend i replaced the door latch and window regulator. fought with installing the vent assembly for hours until I removed the back channel screws, which gave me the wiggle room needed to seat the glass into the front channel. Recently pulled the Harrison Fresh Air heater, pulled the core which was leaking and had a local shop re braze the core. This is a 53 3100 daily driver for my daughter.
