1968 barracuda interior for 1964 plymouth valiant

So I really like the 1964 plymouth barracuda interior for my 64 valiant but the back seat is didferent for the valiant

My brother has a 1968 barracuda. And im wondering if I can get the 68 foam and seat covers and would they work wirh my seat frames for the 1964 plymouth valiant. Has anybody tried this ?

Thoughts ?
