Bottom bracket for DA 7402 Crankset

(Rik O'Shea) said:

Hello,
I intend to replace the bottom bracket on my long suffering training
bike soon.
I use a Dura Ace 7402 Crankset. My understanding from Sheldon's site
is that
this would normally require a DA 7402 BB which is 68-112mm (8-speed
1990-95, Right end of spindle 3 mm longer 112 for 68 mm bb).

Could I use a Shimano XT UN73 Sqr Taper 68-110mm OR 68-113mm with this
crankset ?

Thanks & regards

FWIW, I've successfully used a 107mm Shimano UN-7X with a FC-7402. It
was a little narrow, though my bike allowed it. I think the 110 might
be a better fit though.

The 7402 crank used a 113mm JIS tapered BB, 115mm for Italian threads.
Use a UN-72/3 of 113/5mm length.
