I've never done this before, but I’ve always wanted to modify my mk1, to sport a mk2 connector on the corner, and not in the middle of the unit.

Or I was thinking about making a type of "L" bracket which would plug into a stock mk1, and give you a mk2 harness adapter in the correct place.

Then I was thinking, it would be really nice just to see if I could purchase a spare metalwork for a mk2 to swap out with my mk1 case.
