Anyone know if 1966 and 1967 199 and 232 sixes use the same water pump

[Matt Haas <mhaas@xxxxxxx>]

I was looking at my parts book this morning to see if there's a water pump 
difference that's causing me to have to step the heater hose going to the 
heater core down from 3/4" to 5/8". It turns out that there are different 
water pumps (and heater cores) for 1967 and 1968. The part number for 1967 
is 320-7676. Does anyone know if the 1966 pump is the same?

The primary reason I'm asking is that the pumps listed for 1967 and 1968 on 
the parts store's websites I checked are all the same but 1966 part numbers 
are different.

Thanks,

Matt
