I didn't try a hammer, as my "Mutha Thumper", which I would have gladly applied, was at my friend's house on the floor of my '66 BB 'Vette, also with KO's. I used a big "socket" cut from a truck axle nut tool. (Details if you're interested.) However, it's tough to give those wing nuts a good "whack", especially the rear ones, as the "strike" angle is awkward, as we all know.

I live in a very humid environment, so maybe Rick is correct...corrosion and moisture may have contributed to my misery. thanx for all of your thoughts. s
