Why It Matters
The 1958 Corvette used a semi-floating live rear axle on semi-elliptic leaf springs. The normal ratio was 3.70:1, and factory Positraction choices included 3.70, 4.11, and 4.56 ratios. Housing, ratio, dates, transmission, engine configuration, and service history must agree for an originality claim.
