Sold Specs: 3.73 ratio Gov-lock- works perfect 4340 6 lug shafts disc brakes homemade rear cover new outer bearings and seals 9/16 studs Needs brakes, soft lines and brake "tee" fitting. Things to know: This axle is a bolt in for 1/2-3/4 ton blazers, pickups and suburbans, but some modifications will be needed to get brakes to work. The metal piece on the outer brake pad that sticks out perpedicular to face of the rotor will need to be cut off. I cant remember, but I dont think any caliper modifcations are necessary. I thought I completely welded the inside of the cover but it leaks a little from somewhere. Other than the above things, its ready to drop in. Soft lines I used were off a 79 chevette, and calipers were of course eldorado ones, but front calipers will work, you just wont have an e-brake. Im Asking 250 local pick up Edit: If you want, I will include 9/16 studs for the front hubs, you just have to drill them out. I can also throw in McGard wheel locks and lugs nuts if you want.
