Simply put, it doesn't fit. Literally will not bolt up because it hits the bottom of the rear end particularly the ears that are on the 8.5" 10 bolts. I have UMI boxed control arms and my Full Throttle 1 3/8" bar and stock bar bolt up perfectly with no shimming, spacing or grinding required. This is not an issue with my car or setup or me not knowing what I am doing 
It apears they made this to fit the 7.5" rear ends and not the 8.5". It's not an issue that slightly opening the mounting holes will help. It's off by a mile.......
