Some pix as promised mounted in the RCM mount.
Jammin X2 48T diff:
Ofna Spider Diff, 48T

52T spider diff spur. Too big for std top plate mounting holes.
Slipperential, 50T
Shows clearance, just. Don't have an assembled pic as the top plate will not fit over the 50T spur. Needs to be notched out. Also, the slipperential is quite a bit shorter than the ofna diffs, which are already short by a few mm. Basically the top plate needs to be heavily modified to fit, or use smaller spur.
As an aside, got my FLM skid mount to act as mounting plate.
Looks good from bottom:
But Fail on the back side. Didn't know there was a recessed pocket. Totally messes up where I planed to put the mount. May have to talk to Mike/Jaime about getting a custom one.
