Can you identify this wheel?

[sixtyfour]

This is the spare off my truck, it's different then the stock wheels on my 64. The back spacing is 3 1/2" which is about a 1/4" less then the original wheels. I did a disc brake conversion this weekend the the original wheels won't work but my spare works great! So I need to find more of these to run.

Some of the special markings are "K186 15 XX". I couldn't find any other part numbers??? I forgot to get a full front shot but it looks just like the originals.
