What Length BB's?

All,

I need to purchase two (2) BB's for my flip-flop conversions I'm
working on.

Both bikes have English threading, and both have 68mm wide BB shells.
(both are steel)
I will be using Sugino Mighty-Tour cranks on both bikes.

Bike 1: the spindle that fits best is Shimano D-3H. According to
Barnett's Manual, this is 113 mm in length (Barnett's also says that
spindle lengths can vary by as much as 2 mm for a given designation).
Will a 113 mm BB work? Here's one from Biketoolsetc:

Bike 2: the spindle that fits best is a flipped-over Sugino MT-68. I
don't recall what length Barnett's says this is. Can anybody suggest a
suitable BB to use?

Thanks!

Phil
