MKS and 2010 SHO use the same RDU?

[Gofspar]

The EB MKS has 2.77's same as the non-pp SHO from what i'm reading but the door card says the MKS has Axle 4A vs the SHO's 1A. whats the difference?

Need to order an RDU, seems the clutches are dead.

Hmm It does not sound like the Build date IMO!  I think mine says 2A! Dunno. Z
