NC sportsmans had the XR6 engine with a green rocker cover. They had full XR6 running gear (I have the diff from one and a mate has the 94DT part numbered ECU).

XR6 had a red rocker cover.

To check if it's genuine, check the engine code on the compliance plate. It should be X. That's for EB and ED, if it's an EF it may be different. 1994 will be ED or EF.
