How to identify CHRA of K04 hybrid

[Bond]

I have a K04 hybrid from MTM with RS6 turbine housing/wheel and the CHRA needs a new replacement. I've searched everywhere and cant find the real difference between 0025/0026 vs 0028/29 CHRA. From the looks of my current turbo, the CHRA seems identical to PJK04....can someone help me out here.

To the best of my knowledge RS6 and PJ KO4 CHRA are the same. The difference are comp/turbine wheels and housings , both turbos are from the same KO4 family.
