A month or so later I was reading the Kawasaki Vulcan Delphi forum when I came upon a thread about the chrome side covers. I guy had gotten some for his 2006 Nomad from JP Cycles. I ordered the same part number he did. When I received them I noticed they were also made by Show Chrome Accessories, but were a different part number...81-109. Part number 81-109 is listed for "Kawasaki VN1600 2003-2006". I think Show Chrome needs to revamp their applications listing to remove the confusion.
These fit perfectly.
You have to switch over the key lock and rubber grommets to the new side covers on the left side. Takes about 2 minutes.
This side included a chrome bolt.
I think the chrome side covers look better than the factory painted ones. They are easy to clean and seem to fit a little more snuggly than the factory pieces.
