Yeah, just missing the jaggy bit. Its kind of a standardized drive side spacer. Same one on XC,mono, sport etc.
I've had a look and theyre pretty thin on the ground. ActiveSport main site says it has them, but their ebay shop says not. So maybe aye, maybe naa.
I suppose if you are stuck, get a spacer that has the jaggy bit, carefully pry that off(maybe heat in oven first) then fit to your spacer. A bit of glue(5 min pound shop epoxy) to keep it in place.
