Plastic Glovebox liner
Nah. My '74 was built June 4th '74, so, pretty late in the production year (production ended mid-July most years). So it was not a mid-year change for '74. It would have been an option driven deal, although I'm not sure what the option would have been anymore or when it would have started, I'll explain.
So I have 5 of the things. Previously I thought they were all the same, but apparently I didn't look too closely because one of them is slightly different. And there are two different part numbers- #3590655, which must be for the later cars, and 3590298
The difference, from what I can tell anyway, is entirely on the bottom lip of the liner. Which makes sense. The earlier # has flat mounting tabs on the bottom, seen here
Later style with 90° tabs
side by side, later on the right
I say later, but I don't know when. My '71 Dart GT has an interior lighting package and factory AC, it has both a glove box light and a map light, and had what was left of a cardboard liner. My '74 Duster also had a cardboard liner, it was a non-AC car with no glovebox light. So, no idea when the plastic liners actually started.
Before I looked into it again today I thought the liners were all the same, and the later liners with the 90° angled tabs can be mounted in cars with the regular glovebox opening (ones that had cardboard liners). They DO require slight modifications to install in the non-plastic liner cars- but very minor. Basically you need to bend a couple of the tabs in the lip of the dash around the glovebox opening and add a couple clip on nuts. I went over the install with a bunch of pictures on my '74 Duster, which I modified, and my '71, which I did not modify. But the #3590298 box wouldn't require the lower tabs of the glovebox opening to be modified, it would fit stock.
Here's my previous info on installing them, keep in mind this info isn't 100% correct anymore because I didn't realize there was a factory plastic liner with flat lower tabs.

So I'm not sure when the year break was or when they were introduced. But yeah, two different part #'s. The earlier part # would bolt right into the earlier cars without modification, the later part # requires a very minor modification linked above.
If I had to bet money, I would bet the "early" part number is actually for '73-'74? cars. They'd fit '68-'74 because those glove box openings are all the same. The later ones are maybe '75-'76? I know for sure that all of mine did not come out of '76 cars, because I know all the cars I pulled them from were not '76's. I know at least one was a '76, one was a '75, and the rest were likely '74/'75 because that's what I pulled from in the yards. I ran into at least one '73, but I couldn't tell you if that's where the earlier one came from either.
But I seriously doubt they started before '73. I would think they would have been tied to either AC or lighting options, and my '71 GT had both and still had a cardboard liner.
