It lists a double as 116.5 or 120mm.

Joel Metz's TA reference has a double with 118.5, which seems to split the difference.

Lastly, I just measured the TA 344 from my spare parts box and it's only 114.5mm.

A couple of years ago I bought a TA bottom bracket spindle and chainring from Mel Pinto Imports. You might want to check with them to see what they still have.
