Hi ICON........I photographed these 2 suspension discs about 2 blocks from my apartment in Bayville, NY. I was wondering how uncommon it is for 2 discs like this to be mismatched in color. Don't these usually come as a matched pair ? I believe these are Chance suspensions from 1963. Thanks (in advance) for your advice. Please post answers to ICON, so that everyone can learn from this. Thank you.
