I was wondering if anyone new if I could put a combo speedometer/tach part number 70900001 on my 2011 fat bob. The book says it is for a 2011 softail but they are both 5 inch and I do not see any reason it would not work. One more thing I saw a french made video with a fat bob that had that exact speedo/tach installed but I can not find it again on the web so I am pretty sure it would work but dont want to spend the 300.00 dollars if it want Help...

 

You want a 74723-10 for a dyna.
