If you take the rotor in to the NAPA store, they will measure the thickness for you with vernier calipers - not as accurate as a micrometer, but close enough for this purpose.

I don't have a thickness gauge to measure them. I don't need them at the moment. The left front rotor on my car wobbles a bit when you apply the brakes quickly at highway speed, but they stop the car quickly with no pulling. Its been this way since I bought the car in 94 & doesn't seem to have gotten any worse. I do also have a used left front rotor that I bought from Murry Park with light rust on it. I bought it because of the wobbling, but don;t want to change it I don't have to.Then, the NOS pair came along.

Compare that with the original thickness of .8775. If they are within about 25 thousandths of this, they are probably OK to use. If they are thinner than that, I'd certainly try them if you have no alternative, but be prepared to take them back off if the brakes act funny. I don't know what the symptom of too thin rotors is, but from a fade standpoint, I can't believe 25 thousandths would make much difference. If someone else has tried this and run into problems, please report!

Some say this info doesn't appear in the 67 or 68 service manuals. I do know that I bought an NOS pair of rotors some time ago & still in the original Mopar boxes. The seller advertised them as new & never turned. When I received them, they had been just recently turned. The seller said they had some rust & had them turned. I asked for part of the puchase price back & he obliged. Since the surface on one side of one of them is turned quite a bit deeper then the other, I'm wondering if they're of any use at all?

Do we know for sure what year range the Budds were used and were they used exclusively in this range with no other types mixed in? I also vaguely remember a conversation about whether the rotors can be turned at all quite a while back but I don't remember the end result. Also, When we first got ours, my youngest(thinking he wanted to be a mechanic)had the rear drums off and when he put them back on, he left off the long spring that wraps around the outside of the drum. Don't know why it was taken off, but, anyway, I don't know where it went and I'm wondering what it's purpose is and if it's really necessary.
