And yes the D30 is a solid contender as long as you beef it up some and stay at 37" or under tires. Make sure to snag Cherokee one 94-99 cause they are high pinion and have the larger joints in the shafts. You can get D44 760x joints and they are a direct fit in the larger shafts. Older axle are ok but I would steer clear of the CAD (center axle disconnect). The cast part of the CAD weakens the tube plus the 2 piece shaft sucks. If you find an older high pinion with the smaller shafts you can take shafts and unit bearings from a 94-98 Grand Cherokee they are same length and use the same unit bearing(I would just swap the shafts there at the junk yard so you don't have to pay extra for the shafts). But all Grands came with larger axle shafts. As long as the Grand didn't have CV shafts. Cherokee 00-01 had low pinion Wrangler axles steer clear of those. Happy hunting!
Yeah I haven't decided how I wanna brace those rear shackle mounts I was thinking I might land the exo cage on the hanger some how so I am holding off on that until I start the flatbed. I need to order the DOM for the cage might do that tomorrow.
