Front is a D50. A "hybrid" if you will.
Most people will tell you it is a D44 center section. It isn't. It is bigger than a D44, but not as big of as a D60. I am pretty sure it is a 30 spline shaft and it uses D60 outers. Should be plenty of lockers for it.
But fair warning, its an expensive axle to repair, as far as hubs/bearing.
I remember reading something on Pirate where someone shaved the inside of the pig and ran a D60 r/p and shafts...
Rear could be a few things. Either D60, D70 or Ford sterling 10.25
Look at the center section, and then go here
