Has anyone here installed this kit? How far is the grinding needed to get the guts out? I have a brand new Moog K7014 long idler arm (c-body, aka "fast ratio")... and I'm grinding the ID but seems I'm getting no-where. Should I be grinding the entire side away, say about 3/16" down? My newly welded kframe is on a bench now, so, installing the idler arm sway bar, etc as a unit will be easier... hopefully this wknd. T/Anks ahead!
