I wanted to swap my octalink for a square taper. Would the spindle length be the same.

As you will be changing your chainset as well there is no guarantee that the new chainset will require the same length of bottom bracket, you will need to check what is the recommended length for your new chainset.

Hi. Does It Come With The Bolts?

Normally these bottom brackets do not come with the bolts I'm afraid.

Replacement For Ta Carmina Bottom Bracket
12 May 2014
The TA BB I have is "finished" and TA replacement BBs are hard to find (and expensive!). The axle length is 119, shell width 68. Reviews say the TA is "JIS taper". Will the 118mm version here be a good replacement? Many thanks.

As long as you don't mind the axle being 1mm shorter (it will probably not even make a noticeable difference) then yes, this is a good reliable replacement.
