I emailed the seller to ask if they could remeasure the diameter of the front of the center caps, he never responded. So I trusted its metering abilities, even though it didn't sound like the middle of a standard 2.2-inch device. So it doesn't fit the 2.2-inch or the two- and three-inch eights that are more common in the middle, like the Chevy Cruz and many other Chevy products. The diameter of the face is two and five-eighths of an inch in case anyone is wondering. I don't know why the seller couldn't reply me, but now he will pay for all the shipping cost to and from me.
