I've searched but have found no definite answer. Will the Swithback floorboards work on my Fat Bob or any other floorboard???

 

No, it wont (see image below). Routing of FXDF style 2-1 pipes as used on '09 FXDWG models is different (lower):



H-D parts catalog states:

"50500247 Rider Footboard Kit:
Fits ’06-later FXD, FXDB, FXDC and FXDL models. Also fits ’06-’08 FXDWG models. Stock on ’12-later FLD models. Not compatible with frame-mounted highway pegs"

 

Don't know exactly what you mean but Switchback floorboards look like they would work with my V&H Pro Pipe on the Fat Bob...???

 

I don't think they will work with the stock pipes. However, depending on the positioning of aftermarkets I'm sure they will work with some. That's most likely the resaon you can't find a definite answer. Just my 2 cents.

 

Go for the Switch Back boards, you will not regret it!
Change the exhaust to some thing made for an 09 Street Bob.

 

just change exhaust to something compatible with footboards. You won't regret it.
