the spindoctor

i bought an old water pump from someone a long time ago to do a csi swap, and when i took the pump off my car this weekend, i noticed the heater hose tubes are pointed slightly different directions, and my original pump has an extra heater hose. could this be off of a 'vette, or impala? any way to check the part numbers to see what it came off of? i just swapped the csi to my original pump, but i'd like to sell the other one if i can figure out what exactly it came off of.

I know the B-body ones have different hose configs, probably the 'vettes do to.

LT1 f body pumps are all the same..
Far as I know, the vette pumps don't have a bypass hose fitting [lower psgr one]
Different p/n's too for all 3 [f,b,c bodys]
