Can anyone tell me for certain if the Harley Combination Analog Speedometer / Tachometer, P/N 74774-11 will retro fit a 2009 or 2010 Softail Custom FXSTC? It looks like this... Combination Analog Speedometer/Tachometer - Black Dial | Harley-Davidson USA I know I have other options, none as clean as this one. I have a difficult time understanding how/why it would be exclusive to 2011. Thank You in Advance for all your replies. Cheers!
