Yes, you are correct but what you "should" do is pick up a hp 30 front out of an xj and build that with gears to match the 8.8 before you go ahead with just the 8.8 rear swap and pull driveshaft which would leave you without 4 wheel drive going into winter season.
I realize its easier said than done, especially on a jeepers budget, but if you get your front setup first without having the pressure of getting it all back together with new gear set in one night and youd have the stronger hp 30 right away
Just my 2 cent....the 8.8 swap is a bit of a chore as well...everything ive read, having the 8.8 swap hardware weld kit is worth every penny
America will never be destroyed from the outside. If we falter and lose our freedoms, it will be because we destroyed ourselves.
