Hi Phil,

Thanks for looking into this. It seems the soft plug sets the Filling Station, Chevs of the 40's and Jim Carter are selling, all have the same contents.....so all have the 4 small soft plugs and the 4 small threaded plugs. The sets are intended for 216, 235 and 261 and a wide variety of build years.
I can also only spot two of the smaller soft plugs on my 216.....would the other two be for a later block that has a casting intended for an external oil filter, maybe? I checked some pictures online and I get the feeling some 235 or 261 blocks might have two extra plugs on the side of the engine.....near the oil pan?
