9” drum brake retainer clips on assembly line, OEM?

Not sure what your pics are showing.
These are the only style drum retainer clip I've come across.
Used to cut them off with dyke pliers, then smack the drum with a hammer to loosen it from the frozen axle flange.

Yea appears the pics aren’t clear. Here is a clearer one of the piece holding the drums onto the studs on only the front left wheel/drum

wont let me zoom in and upload pics. But if u zoom in you can see little round clips almost look like splines thin washers
