id have to look but I think the 5/8ths part is the hub and the 9 tooth driver has a 9/16s bushing same as rev grip that fits over mcculloch out board rev grip hub with extended bushing on hub ..
cost wise ....either way no matter what I would try save and use the rev grip clutch ..you wont regret it ..even if you send driver to me or someone ...we can weld new sprocket on it ..and I can tell ya how to grid the shoes and cut spring... got to cut spring special length use metal screw hold it to gather no hooks..but I cant tell ya how I grind and cut shoes Lol.. ..mine are set for around 6500 on an820 an7800-8000 for mccullochs ..
