Hey guys, new to the forums here but I need some help.
I currently have a 1956 312 in a 1947 truck, which makes the pump the high fan mount pump (part # B6T-8501-B). This past June, it shelled the water pump. I sent it out to get rebuilt, it came back still leaking. Searched the internet and parts warehouses high and low, came back with nothing (Kind of. Dennis-Carpenter says they have two NOS. They don't - well, not unless they've found them since I tried to get one in July). I sent the pump back to the rebuilder, they had it for a month this time, got it back yesterday and it leaks again.

So, does anyone have a preferred rebuilder they would recommend sending the pump to? I think I can get two cores from the guy I bought the truck from, and I should be able to make this one work for now, but I need a working, non-leaking pump. 
OR, does anyone have a good, rebuilt or NOS pump? (I'll be posting on the classifieds in a minute, as well).

Thanks in advance,
Brad
