A 4 link and chassis mounted steering is not going to work to well unfortunately. 3 link with pan hard works best for cms. You should mess with that kit some more. I haven't seen to many setups where you just cant make it work.
EDIT: looks like a Honcho? I think they might have a different kit for that truck than normal. Talk to the hand bros over on ORCRC they run that setup on their comp truck and it works great
