Well its going to be dictated of whether you can find an axel with ABS. I think some Cherokees came with ABS, but there wasnt alot as it was an option at the time. But that is only a Dana 30, not really woth swaping in IMO.
Other than that there really isnt a whole lot of vehicles with ABS worth swaping.
did the conversion on my eb dana 44. You just need to know a good machinist. Took the abs sensor and ring gear front a 2wd 2003 and machined the hub and the ring so the would fit together, then drilled the spindle so the sensor would pass through it and abs work perfectly.
For the rear an 8.8 abs ring fits directly on a 9 inch detroit just need a little bit of grinding so the ring clears the housing and four weld tack, for the sensor you cut a section of the top housing and weld a flat section at the right place then drill a hole and pass the sensor
