Getting ready to do a 3/4 ton swap. I will be pulling out a 12 bolt and a D44 out of an 80 K5. I think they have 3:73 gears but will check when they are pulled. Only thing they won't have is lug nuts and the front calipers. The calipers are cheap I am just having to keep mine because my new front axle nees them the previous owner kept his so its a bad cyle. I do know that the 10 bolt and D44 have the same calipers. Anyway's I need to know if anyone wants to buy them shoot me an offer if not I am giving them to a buddy to takes a bunch of metal (he works for a brake shop and gets all the old rotors) to scap. PM me an resonable offer if you want them.
