I needed to replace the 10L lock on my AE 3-slot payphone after having removed it, and Old Phone Shop had the goods. While I didn't need the mounting hardware it was handy to have, since it meant I didn't have to dig out the old lock. I had to do a bit of filing to clean up two of the four screw holes, but that's a small price to pay for being able to finally close the door on my vault.
