Of particular difference between 55 and 56 is, as noted, the rear axle assembly. The 55 is a Packard-built unit which uses tapered axle ends with lug bolts instead of the flanged axles with lug studs on the Dana/Spicer unit on the 56. Thus brake drums, internal parts like ring & pinion, carrier, and perhaps bearings won't interchange. It might be possible to substitute the whole unit, not sure of what might be involved. The 1956 offered Twin Traction (an early positraction) which 1955 didn't.
