My 1 HP Hayward Super Pump (SP2607X10) is leaking. I'm thinking it just needs new seals since it hasn't been serviced since it was installed new in 2004.

Here is a link to a place I've ordered from before that carries parts for my pump/motor:

It appears I can either order the seals individually (genuine Hayward parts) or buy the "Go Kit" (aftermarket parts) that includes all the needed seals in one package at reduced cost.

Would the aftermarket seal kit be fine? Or should I stick with the original Hayward parts (I noticed #13 on the parts list is listed twice? Does this mean I need both parts? I certainly want to make sure I get all the needed parts.)

Thanks for any guidance and suggestions. Since I've never done this before, tips on installation are also welcome!
