How appropriate that I should find this thread. I am trying to sort out my main ride - a 1979 Canadian built Raleigh Grand Prix. The Bottom bracket is 70mm Wide which means it wants a spindle/axle with a 55 mm central dimension.

The current spindle is a 5T which is 130mm long and sizes 35--55--40. I really would like one that is 32--55--32 if such a thing exists in one of my LBS junk bins.

I have found a spindle with different form of ID but don't know if it is appropriate and hope somebody here can enlighten me. On one side it has the characters C and S and on the other 7 and 21. The central dimension is about 56~ mm.

Thanks for any help.
