Someone did use a later aluminum F body driveshaft, but there are a lot of variables that determine driveshaft length.
I have had to have mine shortened twice, once when upgrading the rear and from an 8 inch Ford to a GM 12 bolt and then again going from a TH350 to a late Muncie 4 speed which was 3/4” longer than the early Muncies.
