Two charts are shown for rear springs. The first is a list of code letters and part numbers from the Assembly Instruction Manual. The second set is from data supplied from my Chevrolet Parts & Accessories Catalog. Another case where part numbers differ in some cases.
The springs vary with application and chassis packages, but there is one thing that is important: 1968-72 A-cars have a different front spring diameter when compared to 1964-67 front springs ("Knuckle Sandwich", Hot Rod, 6/87). 1969-present springs are based on computerized data concerning chassis package and body styles, but the rates vary, in which a softer or stiffer ride is preferred.
Note: 1964-67 front springs can be found on 1967-69 Camaros and 1968-74 Novas, but the spring rates will differ. 1968-72 A-body front springs are used on 1968-70 BOP full size cars, but the spring rates vary.
