76 valiant brougham core support???

[71340Duster]

Can anyone tell me if a core support from a late model Valiant Brougham would be of a different dimension than a core support from a late model Duster? The opening in the core support I have (76 Valiant Brougham) is 25 7/8", I am trying to figure out if a 26 inch would be alright or if I should go after the one spec'd for the Valiant which is 25 3/8" wide? Maybe I'm over complicating this.

Duster/Demon body parts are usually quite different from other A-bodies. How the fenders at headlight houses bolt up might be a much larger issue than the radiator opening.

Okay thanks, that's something I didn't think about. I haven't welded in the support yet, I'd better find out.
