Maverick shafts, while close to the correct length (did not require shortening), are also NOT a direct swap. The II bearing retainer plate/housing end has an odd bolt pattern. The bearing area of the shaft is also smaller than the Mav shaft surface. Machine work WILL be required to use them, you cannot simply use the II bearing retainers on the Mav shafts. If I were doing this today, I would spend the money to have shafts with the correct dimensions made, or utilize an axle assembly with the desired width, and move the perches to the correct location. The second choice is likely the better if you're looking for performance, as it should use better brakes, and larger axle shafts.
