Re:

the 7400 bb was a square taper

Re:

The 7410 was a sealed unit I think. Some people consider the 7410 as being of the same family as 7400, while others see it as quite different and worthy of further distinction. There's often a little confusion

Re:

is the sealed unit the same taper and length as the 7400 cups and axle set ie will it work with the 7400 cranks?

:?

Re:

nah, those sealed ones are good bit shorter

Re:

Re:

How about one of these in a 113mm?

Re:

any idea if that is compatible with the DA taper?

Re:

The DA7400 are 'JIS low profile', rather than standard, so there's a chance the chainline might not be quite right or the cranks bottom out - you'd have to try it but i think the taper is the same angle. Some say they fit campag BBs pretty well
