Tandem concentric bb spindle

Hello to all
I have an old Sun tandem with a concentric captains bb
the spindle runs on 5/16" bearings,at some time this as been replaced with a Brampton ? spindle which is just a little to short causing the crank to rub on the bb locking ring.

My question is are the original spindles still available to run on 5/16" bearings or a modern equivalent.
Kind regards Paul

Sounds like the spindle is too short. Contact Sun,
