OK, had to search.... now I see what you mean
Ebay 73/74 e body bucketsA small lever on back of the hinge. i guess it catches a striker attached on the side of the bottom!
Now I can't talk about that. Just imagining how it works, yes, I guess the lever return spring needing to work attached on diff side it gets its attaching "claws" reversed, just like the passenger side system.
BUT still talking from the B body experience ( and previous E ), the hinges shape/curvature is somehow slightly diff between left and right side of each back. Dunno then if the lever will match the hinge on the other side. Or even if the latch can be attached from the opposite side to the opposite hinge side.
