Quarter glass ?

i have a 72 2dr scamp and want to put 73 2dr dart no vent windows on it. i see the quarter glasses are different from 72 to 73 but they look identical. can some one tell me what exactly is the difference in the quarter glass? fyi i know the door interior top panels are different and will be cutting the top inside off from another 72 and graft onto the 73's.

would the 73 door possibly work with the 72quarter glass?

i know the upper door seal is different also
