I want to install some front shackles (not tow hooks) on my 06 XK. I have had a hard time locating a source. Seems like every time I find a reference to a source, it turns up in a dead end. However, I did find shackle mounts at thesteelarmadello.com that appear to be what I am looking for. Does anyone have any experience with these shackles? Appears the require front bumper removal and trimming of front bumper. I am OK with that. Any issues with quality or installation?
