[QUOTE=Grand Bois;14144103]The "difference in dish" shouldn't make any difference. The rim will be centered between the locknuts if it's built correctly. QUOTE]

This will sound funny, but I actually think he was referring to "frame dish". i.e. the asymmetric offset of the chainstays from the seat tube.

As far as "measuring the adjusters", that won't work. The adjusters operate over such very small distances that even paint thickness would affect the measurement, but also are there in part to compensate for the inevitable, normal frame manufacturing discrepancies that are found in all welded or brazed structures, due to thermal expansion.
