drill you a hole and stick you a roll pin in it so that when you put the door back on you can align it right where it is.....or just drill the holes and use them for lineup...... or use a sharp scratch awl and scribe a mark you can see when you put them back on.
If they close thet good you are a lucky man....when/if you put new weatherstripping on the doors be sure to get the good stuff that will "give" a little bit or they may not close tight for a while....you may have to push on the door a little to close it after the weatherstripping.
