Suitable fan, clutch, pulley for 67 GT500

[mlplunkett]

As a side note on the power steering pulley, it looks like the AF (5 3/4") and the 7AA (5 1/4") could be used as functional substitutes for the 7AC (7") but the smaller diameter would be noticed by an expert. The MustangTek site notes that both the 7AC and the AF are replaced by the 7AA. Both substitutes are cheaper than the $280 going price of the 7AC but I hope I can find a discounted 7AC. Anybody got one they don't need?

You could used the "AC". However, if you're going to do so you're defeating the purpose plus you'll have to play the belt game.  Remember, it's not just diameter but offset.

Good luck with your project. Time to say goodnight.
