Install new stock WP, what else do I need?

Well so far I have this:

1993-1997 water pump P/N: 12527741

1993-1997 water pump drive shaft o-ring P/N: 12553792

1993-1997 water pump gasket P/N: 10128343

Do I need more than one of the o-ring or the gasket? Is there anything else required to install the pump?

Thank
Mike

And no, I dont wanna do the electric WP.

2 o-rings and 2 gaskets. I really can't remember if a new GM pump has a new o-ring on the shaft. Thread sealer is recommended for the bolts (though I have used none before and did not have any leaks). A dab of grease on the splines of the drives before you put the coupler on would be nice, too.
