Complete used kit as taken off of a clean Western Eliminator or 1970 Cougar equipped with competition handling package.
This factory applied paint daub was to remind the line worker that this side was the passenger side.
The bolt measures 11 1/2" long total width and the spacer measures 7" long. These are both longer than what you would find on a 1970 Mustang.
The width of this plate is 7 7/8" at its widest part.
