The total cost was around $2000, that's with me doing all the labor. The diff itself was around $1300, that included shortening, rebuild the posi, new gear set, replace all bearings, new moser axles, and disc brakes. All the parts are listed, frame material, and diff were bought locally. It should be able to handle what ever you throw at it. No u-joints or half shafts to break! I have a few pics if you want me to email them to you.
