depending if your going to change the veins on the cone or not and what sereis yours is you might have to find or use old fastners or bore out the old wholes I bought a really exspensive remer after breaking a couple of good bits and the cone metal was harder than hard to drill through the wholes remed out very easly I had the roter out and the cone out so it was really easy for the most part I think the veins on the main part had the bigger holes for the new bigger fastners... have fun
