Here's the deal on the rear spokes. There are a total of 32 spokes. The 16 that come from the INSIDE of the hub to both sides of the rim are all the same There are 8 outer spokes on each side. The 8 spokes that come from the LEFT side of the hub are just a little longer than the 8 that come from the RIGHT side of the hub. This means that there are (3) different lenght spokes in the rear wheel. 8=165mm, 8=168mm and 16=163mm. The only way to break up a set and not end up with a sack full of all one spoke left is to sell them in sets of four, (2-inner) and (1-left) & (1-right).
In a pinch you could use any spoke in any position because 2-3 threads isn't going to make very much of a difference, but they are 3 different lenghts.
