The driveshaft is specific to either DCT or 6MT due to differences in the transmission lengths. The dimensions of the differentials are the same either way.

The axles are the same between 6MT/DCT.

We install a lot of OS GIKEN differentials and have had great luck with both their precision during installation, and positive reports from drivers. These diffs require a set of shorter output shafts due to their internal construction. PN 33131214068 (or, since they're backordered, lathe cut the splines on yours to the correct length).

You asked me about Cerakote... We love Cerakote for a variety of finishes and it's highly preferred over powder coating due to its thin film, making it far less prone to cracking and chipping, or changing a precision part's external dimensions. For a subframe, it's difficult to Cerakote the entire assembly as the coating wants to flash before it's finished which can affect it's strength and visual qualities. We find that their air cured C-Series works great and can be easier for large items.
