Here are some pics of my ATI C-4 2.92 planetary kit. Bought through Jegs w/NHRA discount. Looks like ATI press a spline adapter in the carrier adapting the GM internal spline to a C-4 output spline then welding the adapter in place. Not crazy about the weld being right in the middle of the support bushing. Will probably fix that before install. The sun gear is hard to see what they did. You would have to weld or spline the C-4 sun gear to the larger front planetary sun gear. As for the front ring gear assy, it looks likes maybe they counterbored the ring gear assy for the torrington and added a bushing? The assembly came with GM frictions to make it compatible with my forward clutch.

A very differnent approach than my broader stuff. He stayed mainly with Ford C-4 components and mated them to the GM planetary and ring gear. The ATI stuff looked a little less "robust" than my Broader so I am sticking that stuff in my stocker and my Broader stuff in my SS.
