Not sure you can see in the pictures but the five rockers in a row are more “silver” in color and are the ones I needed to do this to. The other three are slightly darker and we’re fine. Both left and rights needed to be relieved. Also, the darker ones have the oiling hole drilled slightly further into the cup vs the others. All these rockers are USA made Mellings (at least as indicated on the boxes) These came to me as one shipment when I ordered. No idea on age of these but something perhaps changed in manufacturing.
