I looked at doing this too. 09 Heritage and I'm 6'4". I did find a few kits on EBay US (see M&MCycles and StPaul HD), but the issue that was identified was possible fowling (hitting) with the front guard when cornering. just got a set of floorboards that have different pivot points - http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=230561963329&viewitem=
They just swap straight over - just need to get the rubber inserts out and swap over. Will let you know how it goes.
