Thanks for the info.
The rear hubs have a different part number, maybe the geometry didn't change but they appear to be different. What I ended up doing was ordering the new HRC rear hubs, front hub carriers, split center diff and the tapered drive shaft. I decided to leave the tall rear wing mount as that appears to be what most setup sheets show in use. Looks like my rear brace is cracked too so I got the m2C rear shock tower brace and the alum rear brace. Hope that doesn't make the rear too stiff.
