without knowing the application, weight or hp,
cost wise i would think moser engineering would have a housing & axles in stock for that application. abs??? im sure anything is possible, but you need to deside what brake set up run, drum, disc, stock parts, aftermarket?
knowing the time it takes to swap out a 3rd member and set up a 8.8, I would rather set up a new gear rather than swap members. c locks? bolt in shafts? maybe a gear venders od section might work better for your application.
