Jim, I don't recall what I have left here from many years ago. I still have PB 3rd party posting so the pictures are still there. For shims they don't have to be pretty at all, I have a complete shim stock set with punches. I simply find the low point and shim from the stud closest to it, bolt it up and recheck. Sometimes I might have to shim 2 stud locations but I like this better then the full tapered shims sold. I can dial in rotors very close with this method, I have reached 001" many times and -0- a few. I personally don't like anything over 003" others may disagree and frankly I am getting too old to really care anymore.
The shim stock kits can be bought from any industrial online supplier and most likely eBay. I have been using the same kit for over 10 years now.
If you have any questions reach out to me anytime.

I kinda liked using those. Got real close to 001. Forget how close.

I did my rotor run-out just like Gary.... a couple Diet Mountain Dew cans made enough shims to do the car.
The only way you can ensure complete rotor to hub contact is if you surface grind the inside of the rotor, the hub face, along with the tapered shim.

Whatever works is great. Many guys have told me they used shims from cans or local hardware stores. We used to use paper for shim stock rebuilding Bridgeport heads to remove spindle chop. I like the shim stock since it comes in many sizes I can dial in rotors and lock them in.
