Default When did the double pulley alternator / pwr steer end on 64 GTO ?

I think I use to know the date range when they stopped using the double pulley systems ,
but I don't remember anymore .
Thanks for any known data points.

Incredible John !
Thank You

Was loosely thinking it was before that , like Dec or Jan 1 .
Have known guys to ditch the double belt system and go to single because they thought it looked corny or incorrect.
I think it looks heavy duty.

I have a Skyline Blue 64 Tempest Custom 326 2bbl parts car with full set up intact for a power steering car.
Will pencil it in to check body build week tomorrow.

Fellow is selling a nicely restored 64 Marimba Red Convertible that could use that set up.
He has a lot of the other unique pieces installed on it.
I think it's an early Dec billing date on that car and 11E body from PMD plant. (the GTO)

Yep
64 Car and Driver Ringer via Tenney via Tiemann

Mine does not have a gold cadmium water pump pulley.
I have never encountered one on the thousands of parts car I have surveyed of all body styles and year models.

I think the story behind it is Scott bought an NOS service replacement pulley once and it was plated.
Then he went on a binge with them.
