County Brand</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">County Brand makes a number of replacement parts for our cars (Water Pumps, Clutch Master Cylinders, Pistons, etc.) . It is not as though we have a wide choice of manufacturers, and in the absence of Stanpart, I think County is as good as any other manufacturer. I haven't heard any horror stories about them.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">2.) The pump from your 73 is the "sealed bearing" type. You don't need to lube these so they are pretty simple. The bearings are available. I think there is an article in an old 6-Pack Journal that describes how to rebuild these pumps. This is also pretty simple. There are 2 of these bearings. They are a press fit into the housing. The shaft is pressed through the bearings and housing, then the pulley is pressed on and the impeller. <br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">What can go wrong? Not much, but there are no stops. So you need to locate the shaft in the case bearings so that neither the impeller or the pulley interferes with the water pump housing. A little easier said than done, but it is doable.If you want to use your favorite gasket dressing (Hylomar, etc) you can. Do you have to? I don't think so but it helps keep the gasket in place while you are installing the pump.<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Upgrades. The water pump body is cast iron and is a lot of dead weight. There is an alloy casting of the same pump body. It is more money but it is a weight savings. I think ARE carried it in this country, and maybe some others (BPNW, TSI ?).</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">If you want to race or you just spend more time in the pupper RPM range, the stock impeller is prone to cavitation. I think these same vendors carry an impeller that has curved vanes like a true centrifugal pump. If money grows on trees, then these are nice options to consider. A water wetting solution is nice thing for your cooling system and can help reduce driving temps a few degrees.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Best Regards-</div><div dir="ltr" data-setdir="false">John Cyg</div><div dir="ltr" data-setdir="false">70 Damson</div><div dir="ltr" data-setdir="false">CC52927LO<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"><br></div></div></body></html>
