I seem to have misplaced the connector that connects the water pump drive on the engine to the drive on the pump. I'm sure this is gonna be a PITA to find. Anyone know where I might find one or perhaps have an extra one they could part with?

 

You can get one at the dealer, but it is a pricey thing to lose.

 

10128334. I'm holding one now. Don't remember what it cost.

Put new seals in, too. 12553792. Shaft o-rings. Some non-hardening sealer on the splines was recommended to me as well.
