well, when I cut the back off the other shackles stood straight up and down. Instead of chopping off the hangers and moving them forward, I just made longer shackles.
I did the longer shackles to get better flex and droop on the rear axle.
Now I am running those same shackles, just braced and about 4 - 4.5"s shorter.
Still does alright.
I am gonna link the rear soon hopefully.
