Need Advice re Which Belts to purchase. My AC belt is screeching off and on and I see that the adjustment is maxed out-which leads me to believe that the belt is stretched. That being the case, I want to replace ALL belts on my 64 with Factory /AC and FACTORY 7 bladed fan with NO Fan Clutch. The belts that are on there now are: AC -Gates 7560xl; Alt -Gates 7525xl; Power Steering- Goodyear 15515. What have y'all had best results with? Thanks

The Gates 7560 would be correct for the fan and AC compressor belt. I keep a few of these new on hand ($10) if you have any problem finding a replacement. In fact I have a good stock of the fan and alternator w/AC belt (7525), fan and alternator wo/AC belt (7560), fan & power steering pump belt (15508) all $10 if any one has trouble finding any of these.

Both those belt company’s are great so just replace what you have 

These cars will often make a belt squeak  sound if the front wheels are full extended in a direction ( a U turn ) 

Check the size of the new belt to the older one to see if the old had stretched to confirm your thoughts 

Fresh parts will always improve the car reliability and a good thing 

Enjoy
