Alright, I've got the new spring packs on the perches and everything's bolted up. However, using the OE shackles has caused the springs to force the shackles backwards to the rear of the truck. I'm going to remove the OE stuff and go back to the Calmini Sachkles. This should force the springs to compress, (not be soo vertical) and prevent them from pushing backwards. I only hope the ass end's not sticking up too far.
I'll let you know..
