Thickness of water pump gasket??

[lbszr]

I had the exact problem a couple of years ago. When the pump was toqued down, the housing's flange tabs were visibly bent and I can't believe they didn't snap off. The pump was from smyths, it was a rebuild from a popular rebuild that does sbc's. I can't remember what it was, would remember it if heard it though. The impeller was not close to the quality of a ac delco. The impeller looked like it was from a rough cast, as ac delco looked like a forging, and perfect. I don't have the measurements any more, but I remember the rebuild's impeller measured thicker than the ac delco and could not be pressed on any farther. The one I had was way out, four gaskets might of fixed it if leaks weren't an issure. I thought of it as..... if least somebody is trying to make one fit, and it could fit after removing it and remachining it, then it could be an option when ac's aren't available.
