Tail Light Bracket Question

[SpeedThrills]

I've cloned my 74 Dart Sport into a 70-71 Duster. I've installed the tail light panel, and I have tail lights and the MM1303, and MM1304 brackets from Classic to hold them. Now I see in their catalog these brackets, MM1554. This is a street/strip car with no intent on accurate restoration. I don't have another car to look at. Do I need the 1554's?
MM1303 - 1970-72 Mopar A-Body Tail Lamp Bracket; LH
MM1554 - 1970-76 A-Body Tail Lamp Reinforcement Brackets
Looking again, I see that the 1554's are listed for Demons and Dart Sports. So, I guess I answered my own question, but I'll post anyhow to be sure.

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.

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