my frustration! left? handed lug nuts

Want more frustration? Wait till you try to remove the old studs. They are swedged to lock the drum to the hub. You must remove the swedging before pressing the studs out, or you will enlarge the hole in the hub. The new studs will not fit tightly in the enlarged hole. This is the correct tool for removing the swedging. http://www.goodson.com/Brake-Drum-Swedge-Cutting-Tool/
Or you can use a grinder/cutoff wheel.

PS it is not necessary to reswedge the new studs, although the factory did, and that required another special tool, which I have not been able to locate.
