Cuda/Challenger seat frame compaitbility?

[krazykuda]

Are the seat frames for a 70/71 Barracuda/Cuda the same as a 70/71 Challenger?

I'm looking for a spare set of seats for my 71 Challenger convertible. I found a set of 70/71 Barracuda/Cuda Gran Coupe seats. Can I have the Challenger seat foams and covers installed on the Barracuda/Cuda seat frames, or are they too different?

Also, is the rear seat for a convertible different than the hardtop? I believe it's a little smaller....

Thanks

Fronts are the same, rear are different.
