or swap in the rear end from a GV, it will bolt in, just make sure your gears are the same, the only beef is that you wont have 28 spline axles in the back, but not a big deal depending on what size tire you want to run....
i will have to look into this more. i heard about the GV rear but thought it was a downgrade weaker why spend the time and money. my tires are around 30" might have to start a new thread maybe there is hope for me.
