Okay. I went out in the shop where all my catalogs are, dozens of them, and I found some glove box "fillers" and the one's from a place I forgot about which is "Echler's", the "ch" is sounded like a "K", and from '47 to '72 were only $12! Great, huh? But from '73 to '90 was $99.99!!! With air!! But why they think the years after '72 is worth more I'll never know. So forget them. They do that with a lot of their stuff, some of it is cheap and then the next thing is a million dollars.
So I looked in the NPD National Parts Depot catalog and they had "fillers" from '47 but only to '72 but they were all $12.99. That's more like it. And that's with and without air. But take a look at those and see which one looks like it might work, there's several of them. So the years '67 to '72 w/A/C, p/n K-16100-67A, and '67 to '72 w/o A/C is K-16100-67B both $12.99. But you can go on line and look at them yourself and maybe one of the other ones might work. There wasn't a whole lot of changes in glove box liners over the years, for awhile at least.
And you may have better luck looking for different places on line than what I have.
