i just some some of those +3+1 arms.if you get them tell them they better make sure they send you the right spacer/collars for the hiem joints.they sent me the wrong ones so my top arms dont fit.i gotta wait for the new spacers/collars.2 go on the outside and 2 go on the inside.i only have the outside on in the pic cuz the guy at asr ask me to take a pic to show him what i was talkin about
