Measure the axle you're replacing , the length should be the same .

As above, though on a road frame it may (probably not) have a 118 fitted.
Take the current one of and get teh code on it.
If it D-NL then it is 122.5 modern you need.

It’s a 122 (a little difficult to measure as I don’t have to lock ring removing tool yet). But it’s defo longer than 118mm
However sjs only had the n55 in 115 or 127

Yep, the 3 means the 68mm shell.
Looking at the crank and other stuff, that BB should be in great condition.
Why change.

Or do I just service what I have (just need a new lock ring as that was damaged when removing it)
