1974 Dodge Dart Sport rebuild

A lot has happened to the Dart in the last 3 weeks or so and I will post pics shortly. Right now I have a quick question concerning the 1974 vs 1973 bucket seat frames. I know the
seat covers are a little different (the type of vinyl grain used). The 74 has the sides and back one grain (Oxford) and the insert, a different grain (Shallow Elk) ; while the 73 also had two different grains (not shown with arrows) but they were Coachman and Elk. I really don't see that much difference in grain but there is some. That is not my current situation. I would like to put a 1973 bucket seat cover over a 1974 seat. I have both parts books but I could not locate the seat frame to verify they are the same. Figured I would ask you "A" body experts. Are are the 73 and 74 frames the same; and, are the seat foams the same? Thank you all in advance.
