DOES ANY ONE HAVE A PIX OF AN ORIGINAL 69 FRONT ROTOR. MY ROTORS HAVE VARIOUS SIZE HOLES IN THE HUB (OUTSIDE DIAMETER) NEXT TO THE DISC......I HAVE OWNED THE CAR SINCE 1982......DON....

JERRY, I HAVE SEEN PICTURES OF REPO'S, THAT CLAIM TO BE MADE FROM AN NOS PART, BUT I DO NOT SEE ANY BALANCE HOLES DRILLED. DO MOST FACTORY ROTORS HAVE THESE HOLES? ARE THE REPO'S NOT BALANCED? WAS THE SERVICE PART FROM GM UN BALANCED?........DON

I have both the original rotors on my car, only one has the holes drilled to balance the rotor. I am sure there was a balance spec for the rotors when new, if they were within tolerance no additional machining was needed. Attached is a picture of the paint mark that was only on the rotor without the holes.
