I am building a custom truck based on a Range rover chassis and body, I have come to the stage about working upon a new dashboard and clocks. I would like to replace the original Non working 92 RRC speedo etc with more traditional clocks set in a custom surround. Ive found a nice set of Jaeger Riley clocks that would be perfect, or some series clocks. Did Jaeger clocks built for Austins or series Landys have the same cables and connections. How hard would it be if they dont to adapt and get them working?
