If you don't want to order another carpet, I think I'd suggest the Challenger carpet because it has the molded shape to match your shifter style. Challenger wheelbase is 2 inches longer, right about the same spot where the carpet overlaps I think, so you might have 2 inches of extra overlap. If you don't mind opening up both sets of carpet, maybe you could use the Challenger front & the Cuda rear and you might have the right stuff.
