Hello everyone I'm gonna tread lightly so hopefully you all understand what I'm talking about. I bought some aftermarket knuckles today at my local hobby shop. The ones notorious for the bearing holes ovaling out. I had to try something new. the slop in my stockers are insane! haha. My problem is I can't find a dang hex wrench small enough to fit the pillow ball caps.. struck out at all my local hardware stores.. I'm gonna go back to my lhs tomorrow and hope they have a driver or something I can buy.. you guys have any tips for me on where I can search for a ultra small hex wrench if I have no luck?
