Hustler Sport 48” Mulching Kit

[JustinGaspar]

Hi, first-time poster. I own a 48” Hustler Sport (Model 929133) and am trying to find a mulching kit for it (PN 111164). I have tried searching anywhere I could think of on the internet, with no success. Does anyone have any tips on where to look? Is there any chance the Hustler Raptor 48” deck is the same as the sport? Thank you all for any help you can provide.
