At the base of the bolt? There isn't much there to grip. I suppose I could just clamp the bolt as it is pretty long. I haven't tried. I figured I would ask here first. But even if I get the old ones out, how would I get the new ones to stay in place then?

I guess I want to know if there as an easy way to get them in and out without wrecking anything or such.
