These are a pair of brushed aluminum caps that are 1/2" thick. The hole centers are 2" pattern with a 3/8" pocket in the backside for spindle clearance and this will fit the Showwheel Streeter or Coys and B/G Rod Works. These are much smaller than the other center caps, probably the ones you can't find, if you need any additional help please email for questions at Dashman's Hot Rod & Speed Shop.
