I just did mine tuesday and had the same prob, so I looked for the second set listed in the mods section. This had "balls", but one was the wrong size ( one nut was longer and won't work). I told the kid at the counter that the kits were supposed to have the balls and the kit did not, but these will work if I switch it with the other package, and he let me. I love the hood struts, and it took maybe a half hour, tops. Good luck,
Roy
