Default Base C6 Brake Rotors -different?

I ordered Rear rotors and pads for my Base C6. I received 2 different rear rotors. They look very similar but not exact. The difference seems to be just the lip around the outside of the center hub. I called the supplier and was told that it does come with different part numbers for the right and left. These are not vented or sloted. Why the different part#s.

i wouldn't worry about part numbers but the rotors should not be different from one side to the other.

Rear rotors for the JL9 brakes (base) are identical side to side. They are vented to draw air from the axle side and are 12" diameter x 1" thick.They do not have internal vanes for directional airflow, but have strategically located connector posts to expel air regardless of the rotational direction.

Both rear rotors should be the same.

If your supplier is saying he has two different PN's, one for each side, I'd be concerned that I had the right parts *at all*, because its not that way from GM.
