C-4 Suspension Chart???
A few years ago I came across a comprehensive suspension chart for all C-4's that had all the spring rates for all the different configurations. Can't seem to find it anymore 
Does anyone know where this site is located???
Thanks!

There are two differing geometries, 84-87 and 88-96. Parts will interchange between those years only.

There has been some discussion as to the accuracy of this chart before. Hib Halverson, a automotive technical writer and media reporter, created this chart and there apparently are a couple of errors in it.
For example, on 87's with Z52 suspension, the rear sway bar diameter may not be correct. I found this out when I bought poly sway bar bushings for my 87 coupe. The chart shows a 20mm rear bar and the bar in my car was 22mm (same as the Z51 bar). Most all of the nuts holding the bar in place were very rusty and given the low miles on it at the time I bought it, I was pretty sure that the bar was original and not added later on.
