1963 semi float dana 60 rear axle

[joe dirt]

so came across this axle and have the chance to buy at a good deal...it came factory in a 63 gmc 1/2 ton...6lug dana 60 with 354 gears and powerlock....all break stuff is missing...from my researching i find that this axle is quite rare......the main reason i want it is cause the locker and gear ratio....anyo e have much experience with this axle?.......curious on how to find break parts for it......nobody seems to believe me when i tell them what it is...lol
