Need help identifying these belts!

[Keithry]

I heard a strange scratching/rubbing noise so I traced the source and it was this unit (whatever pump this is). The belt is too old and worn that it slips and I can see belt just not rotating. I see three other belts in the second picture. I would like to replace them all. Can you help me identify the part number for those belts? Also what are those that the belts are driving? Steering pump?

First pic is the York a/c compressor so if you are not using a/c then cut this belt off. Second pic is the PS pump to the far right. Belt sizes are in the owners manual for stock configuration. Mine is not stock so I don't have the numbers handy.
