yep, I got mine off with a small vise grip wrench and the new one on with a standard wrench without removing anything else. It REALLY looked like I couldn't but of course I tried it anyway. Taking the old one out should be easy, you shouldn,t care if you damage it a little
The new one only needs about 1/4 turn or something like that. A crowsfoot is nice I hear, I've never had one, but I've heard that the crow doesn't like it very much.
