Anything for a YZ80 will fit. I've got some sort of cheap chinese ones that are probably the same as the ones I've linked. I had to drill a 5mm hole in one of them for the spring (it had one, but not in the right place), other than that, they go straight on fine. Mine have been on for a good 15,000 miles I think.
