Well i get mine from the pick a part for $60 bucks, out of a 69 ford f250 with 3.73 gears already, pay another $60 on the housing ends, $350 for the axles, and $120 for the T/A aluminum cover with the carrier bearing preload support, the rest i did it here at home with my measuring skills, my welder and a big pipe cutter. it wasn't that bad, i will put a new spool later on but i can drive it the way it is for a long time i am sure!
