I picked up a HP D44 from a '79 Bronco for $50. Had it shortened for a case of beer (shortened exaclty 6"). Picked up a set of chromoly axles for $400 (okay, so they're chinese chromoly...). E-Locker for $630. Gears and rebuild kit was probably $250. All new ball joints, u-joints, bearings, seals, brakes, etc...probably $400. Time to setup it all up and get it ready to go in...not sure, never tracked my time. Total cost...probably around $1700-$1800. Of course I'm also going with a radius arm suspension (Cage radius arms), and it's going into my ranger....
I'm sure that with alot of people going with D60's in their rigs, that their existing D44's are available for a decent price....
