rear seat interchange?

I think all 67 68 69 are interchangeable just a different seat covers(a bodys).
Not %100 sure though. Convertibles are not the same.

For sure the fastback Barracuda is different because the back lays down. 100% correct that the convertibles are different.
This question has came up many times and I don't recall an absolute answer to it.
