Well I answered my own question this weekend. I bought a used touring seat for my Hammer and was a little shocked when I went to install it because the bolt patter was totally different than my stock seat. Little did I know that it required drilling 4 holes in my rear fender to install it! Luckily I was having new exhaust put on my bike so I just had the dealer install the seat while it was in there. So, the final answer to my question is yes. All of the seats will work on any Hammer it just my requires some expected modifications to your rear fender.
