Arthur Gould Rebuilders in Mass. is also good.

Might put up a picture of your "original" '67 8 bolt wp.
Of note, date codes did not begin til mid '67 production year.
Last, in rebuilding original water pumps for owners, you'd be surprised how many folks have given me decades old replacement casting pumps with cast impellers thinking that the pump was original.

Here’s some pics of my old pump....Can anyone tell me if it’s the original water pump to the car ....1967 GTO...and Thanks !

Friend of mine has a 67 and he was asking the same thing, I will ask him what he found out and let you know.

Thanks Rob !

The waterpumpman Is in bloomfield hills Mi has done a few for me and some friends.you get back your water pump with new seals properly clearance impellar i have 20k on my rebuild from him..My puter wont let me post a link..

MUSLCAH, while the pump pictured does have a cast impeller, it is an early aftermarket pump housing without the correct raised casting numbers.

When was your '67 built?

Nov 66

Will check original 8 bolt wp castings. that early, it will not have a casting date.

Much thanks for that !

Sent ya a PM.

My '67 was 14 years old when I purchased it, I don't know if it had the original water pump at that point or not, but I did replace it early on. I found a reference that the correct casting number is 9782482, which is the number on my pump, but it is date-coded B128, indicating February 12, 1968. I'm assuming that so long ago, when you got a replacement pump, wherever I got it at the time, rebuilt Pontiac water pumps were widely sold.
