The set is as new and unused in its original box half of the label is gone so I don't have a part number but application is listed on the half that is still intact see photos. There is a small paper stating there are special washers if caps are to be used on a Dodge , Plymouth or Studebaker these are NOT present. Also using the label they appear to be pretty universal and look to fit most 5 on 4 1/2" and 5 4 3/4" wheels Ford , Chevy , Olds Pontiac , AMC , Mopar and Mercury. Based on the label these must be from the mid 70's Very cool period piece that would add a cool little extra touch to any car.
