Would it just be Tange 68/113? No idea how important sizes are or what other variability there might be in these things. Come to think of it I could well have had the UN300 put in, and the UN55 was what it was replacing..
Also, how much room for variability might there be in the BB length - would 68/110 or 68/115 work ? Can find both of these on the bay.. Can also find a 113x68mm XT BB but no idea how that compares to the UN55. Also keen to know whether it would be a bad idea to buy cheapo crank pullers/BB tools off the net for very occasional jobs like these, or whether it would be worth investing in the usual Park/Icetoolz etc..

You can buy these tools for pretty cheap but get them from trusted brands, ie lifeline, X tools etc. the unbranded stuff from eBay alix etc is utter trash IME

The lenght should correspond with the crankset and/or the desired chainline.
Icetoolz or Cyclo stuff are good enough for me, never been tempted by Park.

Fair play. Tange is my other go to when UN55 is unavailable.
