the 56 powerflite must have a different tailshaft than the 57-up type... they made the interchangeability a breeze for '57-up installations/swaps a breeze, the bellhousing mating surface>trans mount location is the same whether TF/PF for 57'up, the only difference for installation was the cable type, linkage, shift mech/buttons/bezel, and ball-and-trunion size. aside from stall speed difference between pf/tf, the bell and converter dont even require a swap. in fact a powerflite converter with powerflite-friendly rear gearing make for a real nice performance upgrade when a t/f is swapped in... nice 1st gear multiplication and a little more stall by approx 300 rpm.
also, if you dont want to go through pressing roller ball pins, etc... you can simply swap the parking drim from the powerflite onto your torqueflite and use the same driveshaft after a swap. the difference was minimal in pin size, overall was less than 1/4"... i just went through swapping the torqueflite trunion housing onto the p/f driveshaft- pressed the tf crosspin into the pf shaft, balancing it within +/- .001 on center.. worked perfect, but then i played musical park drums on my next trans build... the splines, seal seat etc are identical.. could have simply swapped drums and saved 2 hrs of shop time customizing a driveshaft.... only because i wanted the stepped tube 122"wb wagon shaft instead of putting a straight tube 122" wb shaft out of one of the dodnor desotos or dodges i have set aside...
just pay mind- 57-early 59 drums' seal rides on the drum itself [tailshaft seal] mid 59-up seal is deeper in the tailshaft and contacts the output shaft- the drum inner hub is unmachined and wont fit earlier trans's.... however you can use the early drum on later trans's with no event- late on early will not seat/install.

Thank you for the information on the cast iron Torqueflite and the Powerflite crossmember mounting and the pusbuttons. I believe I have a couple of those Torqueflite pushbutton bezels in my parts stash; will have to look for them.
