got exactly what I expected

Same as what you'll find at a local parts store. Probably made in China like almost every rotor these days but the quality is decent and fitment is perfect.
Yes, I recommend this product.

What is center hub diameter? Trying to fit aftermarket wheels to this rotor. Most wheel applications are for late model cars so a custom fit might be required. What is the center hub diameter to ensure this will fit inside the center bore on new wheels? Also, would a hub centering ring be required?

This 11" Ford disc rotor has a hub od of 2.770". The use of a hub centering ring will depend on the wheels being used. Most wheel manufacturers design their wheels with a centerbore large enough to fit on most cars. Therefore, since wheel manufactures make their center bore large enough to fit most cars, most wheel fitments have a gap between the hub and the centerbore. This gap usually doesn't allow for the wheel to fit hubcentric but rather lugcentric which can cause a vibration.

Does this particular rotor use the same bearings as a stock drum and hub set up or do I have to buy new bearings? My old bearings I just replaced about 6months ago I would like to reuse them.

What caliper brackets do I need to mount GM metric calipers to a mustang II spindle with this rotor? The caliper brackets seem to be listed as Hybrid or 10 1/2" brackets, I don't see an 11 inch bracket. Thanks

This rotor can be installed on the Mustang II spindles using bearing and seal kit number 91031052 and the metric caliper brackets number 91631914. If you already have the metric calipers this should all work together. Another option is a complete conversion kit number 91031944 which includes everything from the hub dust cover, spindle nuts, etc. all the way into the rubber flex lines that go to the frame.
