CAO turns out to be located 10 minutes from my house, so I called him to determine which ones were in stock, to be sure I could get them quickly, since I broke my left peg the prior weekend. CAO doesn't sell direct, BTW, but will give you the name of a local or internet dealer, whatever you like.
I needed front pegs, and the "Classic" version were in stock last week when I got mine. CAO also gave me the name and number of a local dealer (15 minutes away).
According to the distributor, most dealers (including many of the large internet ones) do not actually stock these items, since Highway Hawk makes so many different versions for different bikes. It would be impractical and expensive to stock all that stuff. So, the dealer merely takes the order, passes it electronically to CAO. CAO then drop ships them from his warehouse in Deerfield, IL to your house.
Anyhow, I paypal'd the local dealer on Monday, $43 for the pair of front pegs plus shipping. I also ordered matching rear pegs, which are on backorder from the factory (I was told in advance when I ordered them). I received my pegs at my house the very next day, Tuesday, for $3.50 actual USPS shipping charge (because I live so close by). Sweet!
These guys also sell them, if that is more your style.
