Best Coilover IFS for '71 duster?

Than right now in the USCA, there are 2 mopars that have proven themselves competitive, and one is a Mitsubishi, and the other had a GM suspension, and LS engine. What I'm trying to say is if we want to compete, we need to be more ambitious, innovative, and live in reality. ( Which is not based on some fable of the green brick, or an exhibition car.)
It doesn't really matter how you spring the suspensions, the simple facts are, the brand that we joined FABO to support, just doesn't represent in reality, and we can change that starting now.
We're not very competitive in anything right now, except maybe pro stock, funny car, and top fuel drag racing.
