Well, the spring rates for the Ralleye, Cobra II, and Stallion were supposed to be different from the other cars, but most parts catalogs only list one or two part numbers for front springs for the IIs and those are usually based on either engine or whether or not it had A/C. If you're going to replace those, get the best ones you can find (such as a catalog listing for V8 w/ A/C).

RJS 11-gallon fuel cell, C4 tranny, chrome 16" pony wheels, fuzzy dice, brown vinyl half-top, and painted in the tackiest color ever (harvest gold, that's why I call it "The Goldenrod").
Also have a 2003 Dodge Ram (lightly modded daily driver/tow rig/office/dining room/home away from home/workshop... I call it "The Big Blue Dawg".) |
