Thanks to N2Billet who pointed me to this site...they have all kinds of cool stuff.
The collars are super cool for sure and allow a little adjustment for the stand off placement, Just tap them and thread in the ball mount and they are good to go...the fronts you have to shorten the ball stud a little so its flush on the inside but the rear is perfect. These are the part numbers if you have the Porterbuilt control arms and trailing arms. These are aluminum so I can polish them or anodize them if I want.
