As mentioned above, the case split is 4.10 and down so it should work. The simplest way to do that is to put his posi case in your housing. That way pinion depth does not have to be adjusted. The pinion depth is the most difficult part of setting up a rear (although Dana's have some other challenges with shims behind the bearings and a case spreader if you really want to do it the right way. It can be done without.) And if the limited slip is a PowerLock, total score!
