Question about side chute compatability on Snapper mower.

[Zom]

I have an older SNAPPER self propelled. Model # P21507BE. I am looking to put on a side discharge chute. However when I google the part number 7042965YP, It comes up several different brands of mower. I don't want to end up with a part that I cannot use. I was hoping that some of the experts on here could tell me if ordering one that fits so many models would be wise? Any help is appreciated.

Great thing about Snappers is the decks don't change. Why fix what is the best deck on the market?

You need this part.
