Re: Anyone ever rebuild a water pump?

Not don't agree that the repro pumps fail after a 100 miles, I have experience with a Kanter repro which is functioning quietly and efficiently after many miles, and of course if you have problems Kanter's warranty is pretty solid. I think the choice depends more on whether you can afford the layup time to remove the pump and send it out, or whether you want to complete the job in one day. But for sure I'd not buy a repro pump in a situation where the core was required!

While the pump is out, don't neglect to check the water distribution tube. When changing a pump on the 22nd/23rd series, I recommend first removing the lower bolts the stamped steel yoke of the front engine mount, then jacking the engine up an inch or so with a large block of wood under the front of the oil pan, and then removing the front mount (and replacing the rubber if needed); it makes access to the lower pump bolt much simplier. Also when you remove the pump bolts, don't forget to note which ones require a flat copper washer for water-sealing.
