Sam,

I've used CS5380 for fronts and CS6319 for rears. These will give a stock ride height for a stock BB Chevelle, no AC. If you want a HD spring ride height, like Grady's COPO, you will have to use something more heavy duty; you can use CS5413 for rears and CS5390 for fronts. These are over the counter springs, relatively inexpensive. Eaton sells nice springs, double the cost or more.
