'Enter' key adapter for the C64U keyboard

The stabilizer spacing on the C64U's enter key is wider than the original C64 keycap's. This will allow the key to attach using all 3 post holes. Tolerances are tight and installing this adapter can be tricky. Also, getting the adapter off the original key may result in breakage of the adapter. You may need a tool like a small hand drill to make a hole to remove the posts if they do get stuck.
