A727 Torqueflite questions (for gurus only lol)

Just a point of curiousity, since i know they are'nt a high failure item anyway, but;

Has anyone ever stacked up rear planetaries from a 70's 727 to compare with the newer four or six pinion planataries from a later model, like a 46-7RHE or an 48RHE??? Are there physical size, width differences??

TIA, Lefty71
