The old one is short due to a break. 

 

Hence why I need to know the correct number

There is no correct number as it depends on variables such as gearing and chain stay length of the bike. As I recall the shimano instructions say to put the chain on the biggest ring on the front and back and add a couple of links to that length. It is in the instructions, but that is my memory of it.

You can't do this - an old chain will be longer for a given set of links.  *Surprisingly ,the difference is quite substantial

*Either that I wait waaaaayyyy too long to change an old chain! LOL

I measure it each time - derailleur cage has to be almost flat out at big chain ring and big rear cog (ie the max "tight") and not be too loose at the small chain ring small cog (ie the max "loose").  It is a shit of a job that requires 3 hands.

Bib/Big then add 3 rivets  (remember that one of those will be the quick link if using one) in general.

It pays to measure though, especially if you want optimum shifting across different cassette ranges.
