i think there is a lap over in sn you will have to watch out for. some of these had a hd bushing package in them. it will probably take the 1480 and have to change two bushings in package. only one probably 33 hole cone used in actually about 3 cones. 52 cone is for afx rotor if you retrofit.
I've put lowen 52 hole vanes in 33 hole cones. Just have to drill the missing holes, real easy! When your in there replace the bolts at the back of the cone (the heads wear off) 1480 and 1680's use the same bushings till about 1989
The part n for the 1680 short sieve bushing kit is also B94553. The 52 Hole cones were first available late 2001 early 2002 with the intro of the AFX rotor
