Most of it is related to road doubles. But maybe you can extrapolate from there.
Campagnolo bottom bracket info
Good info.
Keep in mind which position you are going to mount the chainring on: inside or outside to calc BB spindle length.
My FG runs the 48T ring on the inside position for a perfect chainline on the OEM double 68 SS120 BB, but my frameset and rear wheel are not the same as yours.
