which is the correct water pump?

I'm seeing two different water pumps on summit racing for my 2010 base model c6. Do you know which one is the one that comes on the car? Also, does it matter which one I go with? One looks like it's AC Delco and the other is chevy performance. For those of you that have replaced your water pumps, which one did you go with, how much did you get it for and where did you order it from?

Thanks in advance!

Actually, I just looked on my car and neither of the pumps on summit racing look like the one I have. The one I have looks exactly like this on amazon. Can someone please confirm this is the exact OEM one before I buy it. Thanks.

Water pump change in 2009

See what you have now but in 2009 I think the water neck housing went from the passenger side to the drivers side (based on the pulley as the centerpoint).

Why not just buy at your local parts house like NAPA, Autozone O'Reilly's? Then you know your get the correct one and get the metal gaskets. Get the one with lifetime warranty.

I just ordered the one on amazon. It's the ac delco original pump and brand new.

Does anyone happen to know the tread size of the water pump bolts? I want to buy 6 studs and thread them into the block to get the gaskets and pump on there and aligned, but I don't know what size thread the bolts are.
