Can anyone confirm the part number for the 8.1/496 Horizon impeller kit with wear plate? I searched and searched and can't find a definitive answer, I have also found impeller kits that just contain the impeller, wear plate, and gasket... Then another kit includes a new plastic housing. Any reason to change the housing out vs just the impeller and keeping the heavier duty housing already on the motor?
 
I’m in the market myself after spending 12 hours standing on my head replacing impellers only to find I’m not pumping water. I should’ve just done the research and gotten them. I don’t know if the plastic housing is compatible. It could be - I just don’t know. MY friend’s 96 330 has a plastic housing.
