Can anybody tell me where I can get those little rubber bungs that are on
the DL650 OEM luggage rack and that the OEM top box sits upon?
Is there a part number or has anybody come across a DIY substitute?
I Have to thank you my friend you were spot on these Givi rubbers are perfectNot sure about an "OEM mounting plate", but if you have a Givi top case mounted on a Givi mounting plate E-528, as I had installed by Aurora Suzuki (Seattle) on my '07 DL-650, I had the dealer order me a bag of four (4) rubber dampers/grommets (bungs) as spares. These grommets were ordered by the dealer under (theirs, Suzuki's or Givi's...?) PN: Z126 to replace several grommets that I lost after (carelessly!) removing the top case and not noticing that the "bungs" had pulled out of their mounting plate sockets and were still stuck to the bottom of the case. The cost of this 4-piece rubber grommet kit in 2008 was $2.50.
See the following Givi website for a photo of the E-250 universal mtg plate which shows the 4 grommets in place. I believe the E-528 and E-250 mtg plates use the same grommet in this application.
