Does anyone happen to know why certain flush mount fuel gauges and digital speedo/tach combos fit '08 and up Harley and not '07? Or is it simply a marketing thing an they will fit just fine on my '07 night train? The specific part numbers I'm referring to are 75014-08 for the flush mount cap/gauge and 74720-10 ( I believe) for the speedo. _______________________________________________________________ Never mind. I talked to the dealer and apparently it all has to do with the connectors and the newer digital speedo doesn't calibrate correctly with an '07.
