Thickness of water pump gasket?? - ZR-1 Net Registry Forums

Ok, so I put the new water pump on and torque the bolts down. Go to spin the pulley and it won't budge at all!

So, I take it all back apart and put the old and new side by side on the bench. The impeller is within 1/32" but the gasket thickness between what was on there and what was included with the new pump is 1/16" thinner on the new one!

I pulled a spare gasket down and it's just a bit thicker than the new one but still thinner than the original.

Anyone know what the original ACDelco gasket's thickness is?
