I bought a strut removal kit at Pep Boys a few years back that contained everything that I needed to get the old nut off and new one on. It has different sizes depending on which end is put over the nut, and had an insert for even smaller nuts, which I never have used. That part you could hold with a large crescent wrench, and had a large center hole where various long hex or torx wrenches (also included) could be inserted to hold the strut rod. I don't remember the cost off hand, but do remember it wasn't very expensive.
