bumping this thread because I bought some today.
I found a Polaris dealer local and called them about the parts. They were able to order some for me. At 15 dollars a piece, (they come as a pair) I thought they were a bit pricey.
They do look like they are going to work better than the worn out originals. I'll get them mounted and probably painted up to blend in better.
