Don't know what prices you were finding and how immediate your need but...Not currently in stock but "available soon" direct from Ardisam for $35.54:https://ardisam.com/8920-rotor-centrifugal-clutch-completeFree shipping over $35.At the Eskimo site couldn't find a 2003 year model for a Mako but plenty of parts though with different part nos. https://ardisam.com/parts?brand=eskimo There does not appear to be a full assembly, just shoes and springs (now discoed). Since Ardisam is the actual vendor a call to them might be worthwhile to A: Insure their 8920 will fit your drill and B: Perhaps they have one laying around that they could ship now
Thanks for the info guys. I've been checking every day to see if they got them in yet and just saw they're in stock now just so I placed the order for the complete clutch assembly and got the free shipping. Now to wait for it to come in the mail.
