I took some picutres of the BB. Look at the side near the chain ring. That is the damaged part and where the bearings fell out.
That measurement is way off. You cant measure bb spindle length without removing the cranks.
Your bb may not even be broken, it might have just come loose.
Look, if you really want to do this yourself then sooner or later you will have to get your cranks off and get that bb out. In this case you will need to get your hands on the tools to do it. When the bb is out you can make a proper measurement for a new bb, put the old one back together, or whatever.
