Jchas,
Here is the link to the Raptor Seat Warehouse kit:
http://seat-warehouse.com/product/s...hustler-raptor-and-sport-zero-turn-mowers-xx/
You can use any of them and add a half inch spacer below the other kits and they work just fine. Only difference between the others and the Raptor is the addition of the adjustable seat track and a seat switch harness extension.
If you don't need the additional 40 dollar adjustable seat track. Add four half inch solid spacers with 5/16" holes thru them and mow on!
