I too would like to see pics. with all due respect Prof Honeydew, if the BB shell is 73 the OP needs a 73mm bottom bracket like a older MTB may have. I suspect the issue is that it inserts from the rightside and therefore the flang rest a bit too fat to the left.
is this it? can you flip the eccentric over so the adjuster is.... OH sorry that wont work then your spindle will be backwards PICS!!
