Bob, if you don't find any contact Thunderheart. Back in 03 I put the extensions on my Mastiff and got them through Thuderheart. Good people there. Don't remember what they cost though.
Don't forget to keep an eye on Shovelheadkicker on eBay.
Ohhhhhh........ Disregard, I think I remember you have some of those fancy forward controls on your bike don't you? Might want to list that in your first post.
