Re: 2007 FXST Floorboards? - details with H-D part #s
Unfortunately, technical difficulties are keeping me from posting my detailed reply with photos, etc. However:
The bottom line is that Agro is 100% correct. All you need to do is replace the standard footpeg mounting brackets with the floorboard mounting brackets from a Fatboy or other FL softail. They bolt right up using the existing three bolts.
For my 2007 FXST Softail Standard, I used the stock Harley mounting brackets from the same year Fatboy:
42431-00 Footboard/Brake Support (=right side mounting bracket)
33630-07 Footboard/Shifter support (=left side mounting bracket)
For the actual floorboards, I used:
50621-06 Footboard Assembly, Operator (x 2)
50674-05 Shoulder bolt (x 4)
The only part that isn't compatible is the brake pedal (it doesn't clear the new bracket). I used an aftermarket extended-reach pedal (Bubba's), but you could also use:
42597-00A Brake Lever
42416-06 Brake Lever Pad
I also elected to switch to a heel-toe shifter. This required:
33668-07 Footlever Assembly, Gear Shift
33895-82C Shifter Lever and Screw Kit (x 2)
34611-64 Shifter Peg
I believe this will work with any of the FX Softails (narrow 21" front wheel and footpegs instead of boards).
Everything bolted right up with no problems other than the brake pedal. The jiffy stand, brake reservoir and even the stock shifter all worked with no modifications (the heel-toe shifter mod is optional).
I am 100% satisfied with this mod. It looks perfectly "normal" since I used H-D parts from the correct year. The boards are in the right place (same positioning as on the FL softails) and work perfectly. I could not be happier with the results, both aesthetically and functionally. And, BTW, all of the parts I purchased were made in the USA (pretty rare nowadays, even for H-D).
