I checked and I do NOT have the proper wp pulley.
I've attached a pic of a 1969 429 pulley / bracket set up. Dual alternator belt, p/s belt and AC as well.
Second pic shows the install of the original alternator dual pulley.
What is your application? If not going back into a 68 or 69 vehicle you can use the later water pump, damper, pulleys and brackets which I have along with a thompson power steering pump.
The 460s in the Lincolns utilized a crank driven PS pump and reservoir with a different front cover, crank spacer, accessories and brackets. Scratch that idea.
The last pic is of the later brackets and pulleys for a 1970 to mid 70s application with a york a/c compressor.
These are on my LTD and sourced from a 1970 Thunderbird. Also found in full size to about mid 70's. The thunderbird and Lincolns started using a GM style a/c compressor and p/s pump in 1972.
I will post the remaining pics in another reply.
used 2b RHP.
