Slant 6 Water Pump Core

Holy crap, Batman! How many do you want?

And a little definition of what is a crappy parts store pump, as opposed to what is not a crappy pump, would be helpful. I think I have a pile of these squirreled away somewhere...
It was a new pump from O'reilly. I warranted it out already back in November of last year and the new one didn't make it a year. But yeah, pretty much all parts store stuff is crappy now. I want a Flowkooler, but they're not available till December......if then.
