I just know from reading other threads on converting from BA 10/5 to AX15 and NV3550 in the FAQ. I'd read thru those threads a few time and glean out what further knowledge you can. See what the FAQ threads suggest on this. I wish part numbers for the clutch kits used in NorthJeep's and RichmondYJ's threads were discussed but they weren't. I've done a flurry of clutches in the past 3 months and didn't save any parts at all.
