73 Swing, I've gotten one of these for my 69 Valiant 100, the "shelf" came from from a 68. I'm going to try to get out in the garage this week, I'll try to get some pics.
Remember, the dash structure is different at the lower edge to mount these
little shelves, you might want to grab that too, although I suppose a guy could hammer some flat spots where they mount, but why do it the hard way?
These can also be found in 67-69 barracudas, not sure what determines which cars got them.
Another goodie for Valiants is to rob the plastic glovebox liners from the 73-76 Valiants, Dusters and Darts, much better than cardboard.
Also, the plastic splash liners in the front wheelwells/fender area. Which don't fit barracudas, for some reason.
On these, the Valiant models differ from the Darts, due to the difference in the shape of the trailing edge of the front fenders, i.e., brand specific.
Happy hunting.
