If you don't get these served up to you on a platter, you can always rough assemble up the axles and hubs and spacers,
and figure out the centreline through them and the bike, and the chain runs. And work out any offsets from there.
I've just been doing this with an EW, since the jumble of wheels and axles and bits didn't seem to entirely match up with anything.
And they'll need relacing to get workable tyre sizes, so measuring is one thing I'm not going to omit...
Cheers.
