Thanks for the pic! That is exactly what I was describing and exactly the same setup I have on one of the planes in my fleet. It came off a chainsaw, but I just can't remember what brand/model now. I have also made them from scratch though; just buying the washers required. If we knew what chainsaw they came on, it would be really cheap to buy the pieces. If I get a chance, I'll research it some more later. It would be good info for us to have in any case. You never know what future projects might entail....
