Complete Water Pump Housing Kit - Sierra

Wish it included an assembly diagram. My motor is quite old and I am not sure everything was correctly assembled by previous person who worked on it.

the quality of the pump and seals looks good but it is aftermarket and comes with 2 different seals then the oem pump and no instructions on where the extra parts go there's a 2 1/2 inch o ring that's new and a lower gasket that's also new and unexplained and the key-way for the impella was not in my kit even thow its shown in the image the extra seal is bottom right and same with the O ring bottom right and the key way in the gasket bottom right not in kit and no instillation instructions

Excellent
