Stop in for a cup of coffee

I guess there's some rare water pump for LAs that the outlet is on the opposite side, its aluminum. Someone was talking about it the other day on here. I apparently got lucky and have one

That was an aluminum version to replace the early cast iron water pump....

On a 73 car, I'm sure it will be the 70 and later standard aluminum water pump....

The lower radiator outlets are reversed between 69 and earlier and 70 and later....
