04-05 sounds about right, if you find 05 on the attachments it's likely an 05. I was looking at these a year or so back and IIRC most were 04/05. I was offered one for 6K and I kinda wish I'd taken it.


I haven't had the privilage of tearing one apart but I'd have to imagine there is some sort of adjustment in the linkage. You may have to remove the fender pan and inspect, may just need to be lubricated.
