Could it be that the frame is wider in the bottom bracket area so the BB cups sit further out on the axle?
It could be but it’s much much more likely that the crank tapers are worn.
Was the size marked on the bottom bracket itself? Could be you ordered a 107mm and were sent a 103mm? Actually, don’t think the SKF B.B. is available in 103mm.
