You could contact Independent4X in Richmond (Ashland), VA. They are the ones that adapted a 3" body lift kit for Nerve_Gas. http://www.vehicross.info/forums/member.php?u=1735
Here is their website. https://www.independent4x.com/merchantmanager/index.php
I sent them a message asking if they could look up what kit was used and what modifications were required. I'll let you know if/when they respond.
He also had a 4" suspension lift that toasted his CVs which were never replaced. It's a shame his VX was wrecked since we could help him out with a diff drop now.
