Dura Ace Bottom Bracket Replacement - 7410 Cranks

Trying to replace the BB on my Merckx Leader and I can't figure out exactly what I need. Hoping someone can help.

I've got a Dura Ace 7410 crankset on the bike that I want to keep, and I'd prefer to get a new Dura Ace bottom bracket, but I can't find a 7410 BB anywhere.

Any ideas?

I have an Italian threaded 7410 BB in EXC condition. I am willing to part with it.

To the best of my knowledge a Phil BB would be the only thing that comes even close to being close in size.

You need a JIS square taper bottom bracket with a 103mm spindle and Italian threading.

7410 bottom brackets have been out of production for years, you can wait for one to come up on ebay, take Jiangshi up on his offer, or buy a new replacement that meets the above specification such as a Phil Wood or and IRD.
