Yes, so was the stock 26" radiator I pulled out of a '74 Dart, and it dropped right in. And so is the 26" Champion radiator that's in my Duster right now. 26" core plus brackets. I didn't move anything, not the battery, horns, nada. Just drilled 4 new holes and made my life super easy by tacking the nuts in place just like factory.
These cars came with an option for 26" radiators. Yes, they had slightly different radiator supports. But the frame, inner fenders, and everything else is in the same place. I suppose its possible that the C-body brackets are different enough to require some trimming, but we're talking minor issues.
