Correct rotor?

Of the two rotors in the attached photo, which one of these is the correct rotor for a 1990 SC?

The one on the right with the black/rounded hat (46mm height) is the same as what came off, but doesn't match the offset as specs listed online.

The one on the left with the unpainted/square shouldered hat matches the dimensions listed online/in this photo (50.9mm height).


They both have the same part number on the boxes... Autozone 5468. I think the one on the left with the square shoulder (50.9mm height) is correct, but again, the other style came off the car...previous owner before I got the car, etc.

Great, thanks.

Now all I have to do is locate one more new like the left.

Did they both have the same center opening diameter?

I've never seen a rounded hat one on any of my SC's...nor any in the junk yards.
