5.9 grand Cherokee limited swap to 1969 dart

That Dana 44 in the zj I believe is the dana 44a. There is very little after market parts for them. If you have a 98xj it should have a 29spline 8.25(comparable in strength to a 44)im running 36" tsl on my 99xj. unless you have abs, then its a Dana 35(weakness). Did you plan to swap over the link setup and ditch your leafs too?
