Drivers door glass in both my 52 and 53 Mercs is cracked so bad I don't dare try to open the window. Crank mechanism is seized up solid anyway. I'm considering the possibility of replacing the glass myself. Assuming new glass is available locally. I've never tried this job before and have no idea how its done. Watched a few videos on youtube applying to fifties GM trucks but have not found one specific to 52-54 Ford/Mercury cars.
