I know they aren't Viper seats but I have SRT8 Challenger seats for my 71 Challenger. Test fitting them, they will require me to cut the hump on the side out and level the floor or possible drop it a bit. I'm 6'2" and would be looking at the visor if I didn't. My project is a custom pro touring project so I do not care if I cut the floors. If your's is more or less an original that you don't want to cut up, you might want to trial fit first. Most of the OEM newer seats fit high. Aftermarket and some of the older non electric OEM seats are much lower.
Of course a true Viper seat will also not flip forward I would assume? Or at least all the way forward like you really need for a Challenger/Cuda to get to the rear seat.
