The last time I looked for matched belts (bundled together), I couldn't find any. What I did discover, however, after sorting thru Napa's supply, is that each belt has it's own unique markings depending on where it was cut from the master roll. Luckily, I found two that were cut adjacent to each other. Because of the long span between the compressor and the alternator on B and RB engines fairly equal tension is especially important. Often, the pulleys don't line up too well, which also contributes to belt wobble and throwing. At a car show the other day, I noticed that a Jenson Interceptor had a (factory appearing) tensioner mounted about halfway between the compressor and alternator (JI's have RB engines)--a good cure for curing belt wobble.
