I might have one but I'm not going to try and dig it out. Try a SBC, some use the same water pump pulley as the smaller Pontiac. You can buy one cheaper than having someone ship it to you.

Like fireball said. Look for a sbc pulley. I don't think a pontiac ever used anything that deep.

MB125 , Didn't some years ,before '69, use a water pump with a longer shaft that would require a pulley with the deeper backspacing so the accessory belts will line up properly?
I remember seeing something written to that effect but not sure where.
