Okay folks here is another rebuild for '80 CJ7...what I will be doing: Replace 6-cyl with AMC 360 (from '85 Wagoneer), will keep T-18 trans, D300 transfer, AMC 20 rear axle has one-piece shafts but will get either Ox-locker or ARB Locker, Dana 30 in front will get same locker with 4340 shafts and u-bolt kit for Yoke, tub will be '95 Wrangler, brake upgrade to hydro-boost, I will go to 35" MT tires. The rear frame rails are rusted through and will need support plates welded on and a replacement rear crossmember. I intend to use a one-inch body lift and already have a 4 inch Rough Country "spring under" lift.
With this said, I have to explain why I am not going to Dana 44s or 60s, I'm in Pa. and most of my off-roading has only a minimal amount of climbing, but does involve muddy trails. I believe that since I've already invested in the one-piece shafts and I can control power and speed from the V8 I will be successful with the axle upgrades and 35" tires. Assembled new axles would be great but are costly for me so I am thinking of delivering the existing axles to a shop that will install 4.56 gears and a on-off locker. Comments Please.
