We usually use the Dayco belts from Advance, but never the Driveright belts, the driveright belts are horrible. The Dayco belts are really good belts though and is the same brand that we ship with our supercharger kits.
Also, not sure if anyone has posted up the way to decode belts before, but here is a quick decoder -
For the main A/C / Alternator belt - 5050405
"50" - is the belt durometer
"5" is the number of ribs
"0405" is the length in inches, with the last number being a fraction of an inch, so this belt is 40.5" long
So for the P/S belt - 5030310
It is a 50 durometer belt, with 3 ribs and is 31" long
You will see some belts listed as a K030310 (mainly gates belts that we have seen), which just takes the durometer off and still works the same way for ribs and length.
Hope that helps,
