Does anyone have a picture of an original 3X spark plug box?
Or, are they identical to the modern 3X box?
The first box is Champion X, then 3X, then J7J, then J8. I just pulled these pictures from ebay.
Also, does anyone know when Champion changed box colors, especially from the later blue box to the red box? Thanks
