Oftentimes one measurement is worth a thousand guesses. If you're planning to do very much of this kind of work, you need to buy a ruler calibrated in millimeters.
1. Measure the width of your frame's bottom bracket shell. It's probably 73mm.
2. Measure the distance between your frame's rear dropouts. It's probably 135mm.
3. If you look up the recommended spindle length for your crank, it will probably say 110/113mm.
If all of my GUESSES are right you will need a 73 X 113 bottom bracket.
