Wanted Shimano non-drive side BB cup - 105/600/Dura-Ace

[sjcprojects]

I'm after a non-drive side (i.e adjustable) BB cup. It's to use with a Dura-Ace 7400 BB, but given it was being used with a Campagnolo non-drive cup before, I'm guessing it will work fine with any Shimano one of the same era?

I figured someone might have a spare one knocking around. I can swap it for a Campagnolo one if you want...

Thanks
