==Springs== The stock springs should work fine. As the Rodder's Digest article suggested, you will need to spread the bottom of the spring a bit, because the '58 Pontiac spring pocket is about 1/4" larger than previous years. This car required a spring rate of approximately 300 pounds per inch, with a ride height of 9.5 inches, and a free height of 15 inches. '69 Mercury Cougar springs were used. They were listed at 295 pounds per inch, 10.5" ride height and 17 inches free height. Once a full coil was cut off, everything fell into place. They were also 3.88 inches in diameter, or halfway between the original upper pocket and the '58 lower pocket.
