Suspension Time?

[black67malibu]

I've decided to go the full Pro-Touring rout with my 67 CHevelle. I bought a ls2 with t56 to put in it with wilwood breaks all the way around I've been looking at tons of suspension setups over the past few weeks and have narrowed it down to 3. Ridetech, speedtech and scandc. I was wondering if I could get some pro's and con's or any info at all on any of the kits mentioned above. Im not really trying to piece something together and would rather buy a kit. Also whats the typical estimated time it takes to get some of these products. Im trying to get this car done by the Pleasanton Goodguys event.
Thanks, Tyler
