Drystone has the answer....you can still fit a smaller 68mm BB into it but it needs to be a 73mm shell. The result would be crank arms very close or catching.
Even if the cups go in the spindle is still 113mm in length regardless whether it's a 73 or 68mm wide BB shell. How will that solve anything. If it hits on a 113 width doesn't matter now does it. Bottom line is it will need to be longer to clear and work properly.
Threading a 68mm BB into a 73mm BB shell is not the right thing to do either and hugely poor advice. If it's a 68mm BB with a shoulder on one side it will throw the hole thing off one direction once installed....bad, bad advice. Is this to be a wall hanger or a rider?
