If you can get them separate let us know what they cost. If they are the same as the ones on the windshield they are friggin nice clamps, I'd like to get a couple for mounting lights. I am surprised it broke.
If you cant get any there at the dealer I ran into some polaris clamps that are similar they work great but you cant use all the rubber that come with it I cut a small section to cover what I call the foot side. This week im building a basket and doing some load testing.
I though it was just to hold the clamp together for shipping. I used that area of the clamp to run the wire loom coming from the Sasquatch light down the roll bar to help hide it and holds it behind the bolt. Looks real clean.
Don't throw them away, they will come in handy for something.
on the rubber piece, take them out and leave them out. I learned that the hard way with my roof on p2 flapping in air on interstate. Dealer actually found lost bolt of clamp (i thought my clamp broke). I took the rubber pieces out, tighten all clamps and have done 90mph plus with no troubles on long haul now. I have full windshield and hard roof. Dealer should have some clamps. Hope this helps.
