C1 A-Arms
 

Is there any one on here that would consider themselves a C1 expert? I looked at a full set of A-Arms for a 1st gen that have all the correct mounting points but they are not stamped steel. These are made from bar stock and steel plates. The big kicker is that they have GM part numbers on them. Could they possibly be factory Corvette race parts? These are still new with a little piece of the paper tag still wired to them. One has an embossed metal band looped through one of the kingpin support mounting holes. Any help would be appreciated.
