Broken GM Glove Box Fix

I got a job from a locksmith company I work with to make a key to the trunk of an older GM vehicle. I was in a hurry that day and as I was taking the glove box lock apart to get the last 4 cuts of the key, I somehow broke the ears that retained the cylinder plug in the housing. That of course meant the cylinder plug would not stay in the lock housing. Looking for a way to solve the problem (I did not have another lock on the truck), I noticed that the back of the plug has a groove cut around it to accept the “ears” of the retainers.

I measured back on the housing where the back of the plug stops, and drilled a hole in the housing in line with the ridge on the plug. I then screwed a sheet-metal screw in the Housing and into the ridge of the plug. It’s the same principle as a set screw holding a mortise cylinder. I put the glove box back together collected my money and went on to the next job.
