I am rebuilding an 8.25 rear axle with a Motive Gear rebuild kit. It currently is a 2.45 gear set and carrier. I have a lightly used set of 3.55s from a 2004 Dakota, I also have a late model (29 spline) carrier that is brand new for next to nothing.

Item one: To get this to work, I need to have axles made since mine are 27 spline stock and thinner. According to the Mopar Action article I have from several years ago, the length remains stock, but I need to have it cut with the late model spline and C clip groove. I like this option because I get some stouter axles and more splines out of the deal, plus I could order them with the smaller Jeep register to center the rotors on the GC disc brake kit I am installing. However, I am apprehensive because I have never met anyone who was done this mod. I would hate to order the axles and get caught by a "gotcha" which renders my new axles useless.
My alternative is to get a 27 spline MP Sure-Grip (or other brand) and keep my current axles. I would need to open up the hole on the Jeep rotors, but that will be a rare need. Behind a 350 hp V8 on street tires (255-275 BFG Radials) will a 27 spline setup with stock axles be sufficient? The car will rarely, if ever see the track as I am building this for the street.
Just trying to decide my direction before I order axles. I have no problem going with plan A (Late Model Carrier) as long as I am not going to run into a bunch of problems along the way.
Item Two: I have never rebuilt an axle before. A buddy of mine helped me take the axle apart, and he was surprised to find the shim for the pinion to be placed between the housing and inner bearing race, instead of between the bearing and the pinion gear itself. Where is it suppose to be, and do I need to change this shim since I am changing from 2.45 to 3.55 gears?
