You need to determine what the difference in width is between the two different rear housings. People can give suggestions, but since things have been changed, it's best for you to measure everything on your truck for accurate numbers.

Install the rear end. Install some wheels/tires that will fit the rear end. Reverse calculate using the dimensions from those wheel/tires. A straight edge across the back lip of the wheel to the back side of the wheels mounting pad is the 'back-spacing' of the wheel. The outer-lip to inner-lip dimension minus 1" is the wheels width.
