Compare the specs of CC655 and Precision SP08055 springs. The same specs.
The SP08055 springs are available through Oreillys. I didn't check anywhere else.

When I replaced the springs in my Avanti with CC655's the front end came up about 1.5 inches. This was actually more than I expected but it made the car capable of driving down our local highways without bottoming out on the stops and jarring my back teeth out. Some of the expansion joints in the frozen north country where I live are pushed up 2" or more.
I ordered a set of CC661's and measured them against the springs I removed. The unloaded difference is about 0.5" lower than 'tired' stock springs. As the article points out with a 0.5-1.0" spacer these may be just the spring I need to get the ride height down a bit to that nice raked look the car had when I bought it... Maybe install them in the spring, along with a couple of dozen other jobs that seem to sneak into the project jar.

How did you that tried these, deal with the "Squared" ends of these Replacement Springs as apposed to the Flattened and Level seated Original Studebaker Springs fitment into the smooth, Level pockets in both the "A" Arm and the Frame?
The squared ends of the GM Springs were designed to fit into a dead ended Link Pocket in the Trailing Arms.StudeRich

Actually this link will explain it better. http://www.moog-suspension-parts.com/moog-cc655

My Avanti II got back the original Avanti rake by eliminating the fender inserts, eliminating the aluminum coil spacers and cutting off (square ending) one coil of some SI stock HD springs ... BUT ... after 6 months of settling, the car dropped another 1 1/2" so the suspension had limited range of travel and almost rode on the rubber stops. So, I bought another pair of SI springs (flattened ends), waited another 6 months and now ride (visually) about 1" too high ... but have range of motion. Oh, and I don't know how SI flattens their spring ends without heating (which is supposed to damage springs). Is anyone getting original rake and suspension movement with their new choice of springs?

Last weekend I had a stroll under my Avanti (it is stored on a hoist) and made some measurements. It seems the front end is about perfect for suspension ride height with the CC655 springs. Compression travel is about 1/3 and deflection travel about 2/3 total suspension movement with the new springs. The old ones were 1/5 to 4/5! My problem now is the rear springs are sagged about 2-3" so the car sits fairly neutral when at rest. I like the raked looked so I guess the next job will be replacing the rear springs with a set of good used station wagon springs I have in the parts bin. I will keep the CC661's (post #4) for my next project.

1. A pair of genuine Monroe Load Leveler coil-over rear shocks
2. A pair of fiberglass rear leaf springs I had made up by Vette Brakes several years back.
PM me if interested.
