As said. The information does not match. Bearings are not included in the collar. I ordered 8 pieces, in fact only 4 will fit. Don't order if you don't like the returns torture. You can't even put two identical clips in each package. Two had different size brackets and one had two wrong brackets. This is a crappy shot of what you actually get. Don't waste your time or money.
