Ron, As Joe Savard has correctly pointed out, '58 springs are 4" longer than '57 springs. I'm virtually certain this is true in every make: Plym, Ddg, DeS, Chrys. - not sure about Imperial, but probably so. You must use same-year springs for your '57. The trouble with any '57 spring swap is that all used '57 springs have been over stressed in use so you may not gain anything or may have cracked leaves. If you get any spring pair from another car, ALWAYS disassemble and clean them to look for cracked leaves. They can crack across the spring (side to side) but the main leaf is most prone to cracking end to end in the middle of the spring! Convertible springs are not necessarily one leaf heavier. The extra weight can be carried by thicker gauge leaves. Count whatever you are looking at.
