Application: fits rear axle with an 8 1/2" diameter, with 8 of the 3/4"studs
Not sure what size you need? Measure the inside diameter your old hub cap and studs or measure the axle and studs to determine the size needed.
Mount: remove old hub cap, center the hub cap over the axle and push into place or use a hub cap mounting tool. Sometimes they would not quite over the lug nuts, so you will need to turn some of the lug nuts to get a proper fit. Caution: excessive force will dent the hub cap.
