Plastic glove box liner

No, the dash frame changed in December 1973, corresponding with the introduction of the plastic glovebox liner early in the '74 model year. So yes it is possible to have an EARLY '74 with a cardboard liner...I had one in a '74 Valiant made 9/73.

Since I have two '73's, I took pictures of the differences in mounting between the two, illustrating why you can't interchange one for the other.

In the first picture you see the cardboard liner arrangement. Note the outermost screw, which threads into a metal insert made into the liner.

In the second picture, you can see the same area on the plastic liner, and note that the position of the screw has changed in relation to the floor of the liner.Also, the plastic liners depend on the metal dash to retain the screws instead of an integral metal tab.Incidently, all the other screw holes appear to be in the same positions other than the bottom two.

In the last pic, you can see the '74/75 black version alongside the '76 white plastic version. The part number for the black liner is 3590655 and the white version carries a part number of 3590868.

So, if you have a cardboard liner from the factor you are likely stuck with it unless you come up with a way to address the bottom bolts.
