The M47R has the same internals, but the whole gearbox is "R"otated on its side 90 degrees. It has a different output shaft I THINK, as it mates directly to the rear diff.

Thanks James - that all makes sense.
I got curious and looked it up - the speedo on a 360 is mechanically driven from the LHF wheel hub, and not the gearbox, as the M47R doesn't have a speedo drive. Damn. :(
