69 C60 366 Water Pump Help

[hudsongt500]

So I have a 69 C60 with the 366 and am looking to replace the water pump. Does anybody have any experience with the FlowKooler on this engine? It seems to be the only thing I can find online that I can be sure fits. Including link and picture of the original - part # 986828(8?) with F22 71 stamped above it.

Are there any cheaper replacements besides this, maybe an AC Delco? Or does anybody offer a rebuild kit?

Also, should I use their thermostat or try to find a cheaper alternative? I hope there's an AC Delco replacement as I'll be needing two...
