Steering Box/Suspension ?s

[jwalk]

I'm very new to the site and don't know a great deal about suspension/steering components. I have a 69 camaro with a stock subframe. I plan on using GW ca with the coilover setup. By doing a little research it seems that the ATS 670 steering box is the way to go. I just want to confirm that before I buy. I also need some input on what coilover setup to run (Reasonably Priced). Any tips/suggestions would be greatly appreciated. I would also like to run a wider tire in the front than 245s...
