UN73

You're probably right Jez - but Shimano stopped making them a while ago, longest is 73/113 unless you want a cr@ppy UN53. Someone might have one they never used...
 
somebody on ebay is selling some UN91 , some of them are pretty long I recall.
 
they are pretty hard to find . becuase cranks were so different and straight in the early days of MTB .
 
Measured everything up again and I actually needed a 73/127! Found an XT one at good old St John Street cycles.
