Marti Auto Works reproduces belts too. I haven't bought from them yet so I'm interested to hear what others think of their belts. They look good in photos.

I am not sure if it has changed but Marti used to take genuine Ford belts (closest modern equivalent) as the basis for and then ink stamping the correct engineering number on the belt. Pretty much the only game in town for reproduction belts .  FYI back in the day most belts were raised letter heat stamped rather then ink stamped. The ink stamp and the indented number heat stamp were used to a much lessor degree over all.

I've seen NPD's and Virginia's belts but I am a bit confused as to which ones to order. NPD lists an alternator belt with A/C,  C4AE-8620-A. The power steering belt is listed as power steering with A/C, C60E-8620-D. The A/C belt listed is C4ZE-8620-B. I thought the A/C belt also hit the smog pump pulley. They do not list a A/C with smog belt for 66. Mustangs Unlimited shows an alternator belt with TE, and a P/S belt with A/C. I think they following is correct for my motor: alternator belt hits alternator, water pump and lower pulley. 15/32"x 40". Power steering belt hits P/S pump, water pump and bottom pulleys. 15/32" x 49.75". A/C belt hits A/C compressor, air pump and bottom pulleys. 1/2" x 61.25".

Why don't you order direct from Marti Autoworks? That way there will be less chance for a wrong belt. The smog application is not very common which to no surprise is why vendors may not list the application.
