It's unlikely the two model years use the exact same York mounting bracket so you'll very likely need to come up with a different mounting bracket. First place to look would be www.kilbyenterprises.com/
But thats it? I found one real cheap. Even the cost of the bracket its still less then half the regular price of a Kilby.
The mounting bracket is key to the whole thing, there are a number of mounting bracket variations due to the changes between model years. Not sure what you mean the bracket is less than half of the cost of Kilby's. If it fits the 2005, great. Otherwise it's a great paperweight.
