Does any body have thoughts about a new water pump over a rebuilt water Pump? New is $34.00 rebuilt is $17.00 at Napa. The FSM said to use correct pump since pump impeller must be compatible with the drive ratio provided by pulley system. The Napa parts person said only one pump was in the book. I did reference a 1982 Imperial. Lawrence R Noska lnoska@xxxxxxxxxxxx Hauser, ID 83854
