my truck has one. did you actually look at it? they are huge. going to take up a lot of room under an abody. im not positive but i think the axle tubes are 4". which will be a pain with mounting points. custom shock plates and bigger u bolts, or custom ladder bar bar or 4 link brackets. i have heard gear sets are a little pricier. you can pick up dana 60 pretty cheap i built 2 for 2 darts they can be put together for cheap too. on i used a take off housing from some kind of truck was like brand new 25.00 on ebay, total cost to my door was under 100. nos cover for 10. i bought new 4.30 and 35 spline mosers, new ends and assembly kit, used moser spool. i had 1200 into it all said and done and it would take some serious power to hurt it.
