I think the N72s were the only preamp that worked on all the versions of the chassis, the very oldest chassis only worked with N72 modules, the others required modification. You can download the one shot instructions and see how they are assembled. I would be surprised if the ribbon connector in the chassis isn't exactly the same as connection in the one shot. There are some modifications as I recall to the one shot modules to allow for the high impedance connection on the one shot font panel.
