I am changing the front accessory drive system in my 1985 c10 to a 1995 serpentine drive system. I have A/C, power steering, a 105 amp alternator, and no smog pump What is the correct size belt that I need?

If everything bolts up correctly you can start with the 95 belt. Then use it to determine if you need a longer or shorter belt. Because you are changing things over there will not be chart saying "use belt X". Be advised you also need to change the water pump and fan during this swap as the 95 pump and fan drive off the back of the belt while the 85 uses the front of the belt.
