How to tell which 1LE rotor is for the left?

hzycamaro · 04-16-2019, 10:49 PM

Hi, I recently bought 1LE rotor replacement. The AC Delco part numbers are

177-1193 = L
177-1194 = R

But after I received the two rotors, I found no part number on them and they look exactly the same. How can I know the left and right?

Internal cooling vanes lean backwards on the top of the rotor when on the car.
