I found this "new in box" rebuilt water pump in my parts closet a couple of days ago. If I remember correctly, I purchased this from my local independent auto parts store (TOP's Auto, Anaheim, CA) many years ago when someone told me that Buick water pumps were getting very hard to find (prior to TA producing one). Shortly after I purchased it I painted it inside and out with engine enamel primer (Yes, I paint the interior of water pumps for corrosion protection).There's very little evidence of pitting (from grit blasting) on the inside of the casting and impeller and no pitting on the exterior surface or the pulley flange. I don't need it now so it either goes in the trash or I can ship it to anyone in the lower 48-states via USPS in a Medium Priority Mail, Flat Rate box for $20. Better yet, I'll just give it to you for free if you pick it up from my place.
