Well, you've confused me.
I'm not looking at asymmetrical BB's, just the Sugino RD-48 and the Shimano 107mm UN series options. I know the width of my rear forks (132.5). Once my Surly shows up I'll know the hubs actual chain line measurement. Hopefully it's between 47-49mm, which I can get close to matching with a 103 BB or a 107 BB.... I think?
Once I know the actual chain line - shouldnt I be able to get the BB correct on the first try?

I don't know where the parts are coming from. My buddy who is a careful hobbyist wheel builder (and a fixed gear racer) is ordering the parts thru a friend's shop... I just asked for a Surly 130mm 32h flip-flop in polished finish, and a pair of Sun CR-18s also in polished. He'll build my wheels with stainless spokes. He has no 406 wheel experience but I totally trust him to get it right.
