Thanks. A friend said he had them and offered them to me. He thought they were for an N frame, but the placement of the washers looked more like they were for a K frame to me so I told him I couldn't use them either.
K Target, appear to be factory. BTW, the stock washers on both K and N stocks are the same and placed identically. The difference between K and N stocks is all on he back strap, portion, from the "knuckle", tapering to about 50-60% down from the knuckle. Look at the width of the shoulder behind the washer. These are K stocks. The shoulder behind the washer is nearly twice as wide on N stocks.
