where to find a 123mm isis BB?

Need to be 68 x 123mm. Don't know who make them and where to get them.
FSA has some 73 x 123mm, does it come with a spacer to put on the drive side?
Any ideas? thanks!

Someone correct me if I'm wrong, but I think you can just put a 2.5mm shim on the drive side.

You might try asking in the mechanics forum

If I put a shim on the drive side, the drive/non-drive side would not be symmetric anymore.

well, the shell is 5mm too skinny, so you want to add 2.5mm on each side of the shell right? The non-drive side BB cup doesn't need shimming though, because it doesn't have a flange. Hence a single shim on the drive side.
