REBUILT NAILHEAD 401 WATERPUMPS---SOLD

I have THREE rebuilt water pumps purchased for my Buick Nailhead 401. All three have been mounted, run for no more that 15 minutes and removed, zero miles driven. WHY, I had immediate coolant leaks. I thought I had the worst luck of anyone with water pumps. FINALLY I found the timing chain cover behind the pump was warped. So, I have these pumps for sale, $50.00 ea. for the standard pumps and $75.00 for the higher volume 5 vane A/C pump, plus the ride. Thanks.
