Paul,
I have been thinking of doing the same thing. I like the glove box lock on the continuation CSX's. I did some research and found the rotating lock they use. It almost works in the superformance glove box without any modification. "Almost" is the key word. i was going to order a new glove box door to modify it, but Superformance said they are back ordered.
Here is the link to the lock used in the Shelby continuation CSX's. It is an old VW lock.

If you find a way to make it work please post it.
Good Luck,
Dan
