go through the thousand threads on this stuff already posted.. blue72 has a ton of info on it.. theres tons of info in all those different threads. they sould all be combined to make it easy to see..
and just for the record i'm a believer in thre RMS system.. had the front and rear in my old dart. i don't care what steering box one may have it will never feel like the rack in the car.... in the end the cost really isn't that far off between doing a stock stle correctly and going aftermarket suspension.. people like to say there is but in the grand scheme of things there isn't.
