These are aftermarket, I'm guessing made 15-20 years ago. You get one drive and one idler. These do have holes for hubcaps. These are for the slightly smaller sized drive axle tab, I believe 7/16 (I have a the larger variety listed separately and shown for comparison in last photo) These are NOS replacement parts and are in minty condition.
