73 Duster / Dart sport door glass question.

[RAT ROD AL]

I pulled the glass out of this 73 Dart Sport, both doors had the steel beam guards in them One glass has 5 holes and one has 7. Obviously nit from the same year car. What exactly do I have ? Classic Industries shows a different amount of holes.
Thanks for any info !

1973 is supposed to be a one-year-only glass. Not sure if the crash beams started in '71 or '72. Could you have a '74+ door on one side because '72 & earlier had the inner door handle in a different location.

I found this on line from here ! I guess I can figure it out . Maybe !

This the window from my son's 73 Sport. Left side. Door is original to the car. Hope this helps.

Yup, 5 hole is '73 and early '74. 7 hole after that. Same with Swinger/Scamp glass. All different guts too.
