When I first started working on this project the coil springs were replaced with TRW stock replacements. I never did care for the rear pair. This car set level but low and sloppy origanally. The rear now sets about 2 inches lower than level. I have the Moog part number for the wagon springs with a spring rate of 145 lbs. The rest don't show the spring rate including the rest of the herd. Is there a web site out there that will give this inforamtion.
