There was a Vendor by Jerry Steins table that had them at Carlisle back in July. He had about a dozen or so on his table. I looked at them quick my 8 year old wanted to go into one of the toy tents so I got distracted and been looking to find who made them and where I can get them. They had an Aluminum housing with bearings where the rubber would go then the center was Aluminum with a brass sleve where the bolt went. I thought they where really neat and would work great on a stock front end.
