I ordered up some of those plastic rivets that come on the Trail Boss where they don't use the fender extensions, but use the same plastic mold the the Magnum 325 does. For only a few pennies each you can plug up the holes in your plastic with these things. I installed mine today. No part number, sorry. The dealer didn't have time to write me up and just gave them to me for free.

I think it looks better than putting the screws back in or leaving the holes open.

Keep on riding!!
