Hello, does anyone know if the rear seat from a 1970 Dodge Dart would be the same as a 1968 Barracuda? Only difference being the upholstery design?

I'll explain why I'm asking...I have a set of factory buckets from a 68' Barracuda I'd like to install in my 70' Dart. They will need new covers installed. While I'm at it I'd like to install new covers on the back seat that came with the Dart. I'd like to order 68' Barracuda rear covers too so that the grain, style etc. all matches the same.
