Topic: shackle identification

[67gta289]

I scored on a nice set of C7ZA-AM springs from a beautiful car that was restomodded.  Also in the deal was a nice set of C6DA shackles in a box of goodies.  But on the springs were a different type of shackle that I'm assuming are aftermarket.  However, I don't want to scrap them only to find out later that they were original to some high performance (competition suspension) optioned cars.

So the question is - keep or toss, referring to the upper shackles on the attached picture.

Thanks, John

The notches in the upper version are interesting but don't recognize them
