Small block water pumps

Actually the timing tab on '69 and down is cast in as well just on the other side, I would just use my old cover and a cast iron pump but my cover is corroded beyond reusing it. As for exchanging the radiator I got a really good deal on it ($359.00 inc shiping) from a hotrod shop on ebay. I am going to ask the question about moving the inlet, but I am also considering the long flex line. I will try the flex line, but at $70 or more the hose location move may be cheaper. So many issues so little time....
