There are pictures of both an 8 3/4 and a 9.3. Internally, I don't believe that there is much that will interchange between the two Dana style carriers. An 8 3/4 carrier for sure won't work with a 9.3 ring gear. The carrier bearings are also different between the two. The splines for the side gears and clutch hubs have a different spline count for sure. An 8 3/4 is a 30 spline. A 9.3 will have a 29 or 31 spline.
