Windshield Stainless Trim Retainer Question

This is what a pack of Year One RX47 looks like. It's suppose to be for 1970 - 1974 Duster & Dart Sport front & rear windows. But I seem to recall a change in the early '70's where the earlier cars had narrower window trim than the later ones. Don't know if that makes a difference or why '75 & '76 aren't included.

The best overall measurements I can get are:

30 with round hole are .850" x .515"
5 with oval hole are 845" x .545"
