Help... I have gone through two water pumps in the last 3 weeks on my 1971 Buick GS 250 with AC. First pump went after running it for years, thought it was just age; this thing was completely shredded inside too. When I put the new one back in, I realized it had the wrong pulley on it, that caused a mis-alignment of the belts, so I replaced it with the correct one. I ran it for about 100 miles and then last night - CRUNCH... this one literary exploded too! My thoughts are that my clutch/fan/spacer are out of balance and causing the water pump shaft undue vibration that it cannot handle, and then it explodes. Thoughts? With that said, I need/want the original spacer and fan for this application, do you have one or both? Tom
