The catalog cross-references this part as an RM21 rotor. If you're working from an older parts book you may see it listed as 99-0739 rather than the number above, but they point to the same physical piece.
We don't have extensive detail beyond the figure placement on this one. If you're unsure whether this is the right rotor for your alternator setup, give us a call before you order.
