Kerry & Charles, According to my local parts guy, they do make matched belts, you just have to find a store that knows what you're talking about. He showed me a number on the belt that I believe is the batch number-- it's not the part #, but a # in smaller print beside it-- that you need to match up in order to have matched belts. Again, according to him, there can be very, very slight differences in length b/n 2 belts with the same part #, because of the batch, when they were made, how old they are, etc. I guess this is only important if you are using them on a double pulley (?). I guess the advice I would have is find a store that specializes or seems to have a lot of parts for old cars, or ask them to let you check the batch #s.
