I've ordered the Sun CR-18 700c rims and Shimano Deore M510 36h front and rear hubs from 2004. A link through Sheldon Brown's website let me determine the proper spoke length for the front hub (297.7 left, 298.4 right) but there's no info on the rear M510. I searched the Shimano website but their "technical" docs don't go into that much detail. Does anyone know the proper specs on the M510 to get me the correct spoke length for building the rear wheel? Should I assume the rear hub has the same measurements (flange diameter, center to flange distance) for both sides as the front hub? This is my first build, so I'm learning as I go. Thanks for your help.
