I also was able to get the DELTA rear panhard bracket on.
With doing all to the rearend changes via new control arm bushing & bracket, the way the rig turns is a huge difference. The best way to describe it is it turns flatter... meaning the rear does not raise up while in a breaking turn. It stays flat & follows the front. No more turning on top of a ball type feeling. I'm sure @nukegoat has a more proper word terminology to describe that.

Didnyou have to grind the delta bracket at all? I had to grind mine down a bit to clear my spring.
