1967 barracuda/dart glove box lock

there is no "catch" on 67 it latches against the dash frame. Unless your talking about the lever that screws onto the lock cylinder?
The glove-box door is different, opened hole for the lock cyl. The standard door can be drilled to accept a lock though.
I think there are only a half dozen or so keys for them. If you have a good supply of keys chances are you'll have one that will work.
