Need a speed magnet for GEM E6 (7.0 HP GE Motor)

Just looking for a source or part code for the stock speed sensor magnet-

Polaris part numbers and MSRP prices:
2005-13 PN:4013651 $139.99
2014-16 (Classic model only) PN:2878971 $138.49
2016-17 PN:4016654 $89.99 but that’s the 6.5 kw AC motor for 48v system

edit: Just saw it was GE its the first one
