I have been to oreilly's, autozone and advance trying to buy a new wp. I asked for a new wp for a 1972 Dart 318 with a/c. Each time the new pump is a six impellers. None of the stores can tell me why? The only way I could get an 8 impellers is buying a re-manufactured. The 8 impellers was listed on Oreilly web site but was unavailable to order. The 6 impellers looked taller (deeper) than my stock 8 impellers. Also the hole behind the new 6 vane is larger and the depth of the housing is more. Now I'm confused of what to do. Do I need to order something different? Just go with the new style 6 impellers which says meets or exceeds oem flow rate. Store can't tell me flow rate either. I really don't want a reman. I only wanted a new $40 pump. Need this week.
