bottom bracket question

I need to replace a bottom bracket cartridge manufactured by Chinhaur and measuring 68 x 116 (size is also noted on the bottom bracket). It has the older style square taper for the cranks.

So far, I have been able to find replacements in the size of 68 x 115 or 68 x 118 but not an exact fit of 68 x 116.

My questions are: Does the replacement have to be exact or can it be off by a mm or 2? If it can be off a bit, which would be the better replacement: the 68 x 115 or 68 x 118?

Thanks

Either one would work,115 being the better bet. Make sure you care also matching the spindle taper,either JIS or ISO. If you stick a JIS taper crank on one for an ISO taper it will go on too far and you could have chainstay interference in addition to chainline issues.

The crank is a Shimano C201. Do you know whether it is ISO or JIS taper?

Also, thanks for the info.

JIS. A shimano 115 will work, but a Campy wouldn't.
