If the trunk is open, taking the lock from it to a lock smith for a key may fix your problem with the glove box. The glove box and trunk key were usually the same on a Ford.
Hate to see you cut up an original glove box. Might be worth purchasing your own set of lock picks and a six pack of beer. You don't need lots of picks, a set of 6 would be plenty along with the lever tool. It is not as easy as you see on tv but can be done.
