I’m thinking Rusty is out of town for a week or so; i’m Pretty sure he had no fitment issues in the rear w/stock suspension & -1.75* camber.
I had to replace my traction arm bolts w/smaller head ones...when I ran 345/30/19 invo’s on 19x12 et38, as I ran only -1.0* camber out back. My pinch point was the traction arm & had about a finger between shock. But I’m 10mm further inward than Rusty.
Hopefully this helps you; as I’m sure he’ll reply when he returns
