      I doubt that the stock front springs were anywhere near 525. The Moog replacement spring catalog lists #5606 for the front, which is 420 lb/in. Rear spring number was #6321 (118 lb/in) or could be #5379 (121 lb/in). The rates of GM's original part numbers might be a few percent different, but I doubt it'd amount to over 20 lb/in difference up front or 10 lb/in out back.
