I have what I believe are a set of vent windows and frames from a 1972 Dart Swinger. I am trying to make sure that's what they actually are and whether or not they have tinted windows, although they look king of "greenish" I was wondering if anybody knew the actual tint code that is listed with the etched logo. The part numbers on the frame are as follows:

R.H.# 2663 528 14552 3-503
L.H.# 2663 529 14553 30603

Those are the numbers stamped into the recess of the vent window frame that is hidden down within the door. Thanks in advance for any help.
