Sorry you had to cut off the escut. the pins shouldn't be longer than the shaft dim. My car had cut nails as pins that weren't dressed properly !
Have seen many (original) cars with something like a dried roofing mastic on the inside of outer door skins probably as a noise attenuator, given that water gets inside the doors.
Re: your window slop, perhaps check the "rollers" that slide in the lower window tracks for wear in addition to other suggestions. Should be more BARN posts on this subject.
