I was unhappy with the original mount system of my Kryptonite Mini-5 U-Slot.

This replaces the aluminium slot on the shackle to insert the lock into its mount.

The part is a first attempt to test for durability. I will report in a few month after using it daily.

I managed to fit it with friction fit (after freezing the lock in the freezer).. I don't think this will ever move, even without the set screw! (unless it breaks!)

I still plan to add the set screw with a heat insert later on, the hole is already there in the model.

You may need to sand the hole to get it to fit perfectly. I had to install the part using a block of wood and a mallet.

The result is a part much more snug than the original, which prevent the lock from moving and eventually loosen the mount over time. I just tried it on a ride, and now the bike is much more silent as the lock is not moving around anymore.
