15" GM Trim Ring 4-clip style (1969 Z/28?)
 

Another garage find:

A used 15" trim ring that appears to be the original GM style with the four clips. It is 2-5/16" tall when measured flat on the table and 2-9/16" deep with the oval valve stem hole.

This may have been a leftover from a pair of 15" 1969 Z/28 wheels I sold off long ago.

Average quality with some scratches and dings. Please disregard the smears and smudges as I had just washed them and they were still air drying when I took the photos.
