Tail Light Bracket Question

So, in the paper catalog, it lists the 1554's as being for 70-76 Dusters and Demons.. On line, they list 1554's as being for 70-72 Demons and 73-76 Dart Sports. They got it a little mixed up.
I'm gonna say my Duster doesn't need them. :realcrazy:

The 1554s go on the trunk extensions to the tail light panel. I believe the passenger side is where the jack mounts also.
