BTW. The "pin" on the large chainring which is designed to catch the chain if your derailleur over-shifts (to prevent the chain from being lodged between the chainring & the crankarm) will NOT be hidden if you are going from a 5-arm to a 4-arm crank, and vice-versa ...
NOT a big deal, IMO ...
When THAT mis-match occurs then 'I' orient the "pin" so that it is to the LEFT of the arm when the crankarm is viewed as being at 12 o'clock.
