Found my dads original 1971 duster!

I believe that the Door felts or cat whiskers are the same for darts or dusters. The difference is between model years. The earlier say 70, 71 are held on with clips on the whiskers themselves as for the later say 72, 73, 74 are held on by difference method which I can't recall. I ran into this issue with 69 style vs 70 something on a dart door skin. The "builder" probably used the later doors as I believe the outer shell (skins) are the same. Hopefully someone else can confirm for you.

Thanks for the info. Duster ones won’t work on darts because the slots stamped into the inside of dart door skins don’t line up with the clips on the duster felts. Even if they did, the slots stop part way up the door near the front of the door, because of the triangle pics of glass that the dart had in that location
Just wondering if there is a way to make them fit or put a different style on or something. It would be almost impossible to create slots on the inside of the door skin
