I just put forward controls on my 11. Harley makes a kit or you can source it on Ebay like I did. The FX softails fit the FLs.
There are a few potential conflicts with the side stand and brake lever. If you use 2000 to 2006 controls you need the side stand
and brake lever from those years. If you find 2007 and later your existing side stand will work and of course you need a 2007 and later FX brake lever. Any FX shift lever will work. Your existing master will work also. The master will slide off the bracket and if you modify the new bracket like the existing one, pretty minor hacksaw work then you will avoid having to bleed the rear brake. If you want Rumble pegs you likely have to go new at about $100 each. There is no small Rumble brake pad available but I think the Slipstream looks pretty good at $40. Call my if you like for futher details. 303-875-0977
