1972 Corvette and 1973 Corvette
The appearance changes were again minimal for the 1972 Corvette. The 1972 model was the last to feature front and rear chrome bumpers, a bright "egg crate" grill, side fender grills, and the removable rear window. This was also the last year for the RPO-LT1 and RPO-ZR1, although the ZR1 code was again used in 1990 and the LT1 designated a new base engine in 1992.
There are 4,000 serial numbers for the 1973 Corvette that were never built. The last Corvette built in 1973 ended with 34,464, but production only added up to 30,464; the missing numbers were VIN 24,001 through 28,000. Rear bumpers were unchanged from 1972, but front bumpers were changed to meet federal 5 mph standards which added 35 pounds of weight to the vehicle. New chassis mounts were added to help combat road chatter and a new hood, with rear cold air induction introduced.
