My alt. pulley had never been completely "straight" with the fan pulley.
So I am needing the 2 spacer lengths.
The one beneath the alt. that the long bolt goes through and the short one that goes behind the alt. bracket that mounts to the water pump. Thanks,,,,Doug

Hi Doug, as I recall pontiac changed the timing cover and w/pump assembly around 1970. They look very similar but the pulleys don't quite line up the same. Do your crank and w/pump line up? I have seen folks change from old to new styles sometimes mismatching parts. Do you know which you use?
