The '71 and '72 Corvette were much the same. Due to a 1969 labor dispute, sales were extended. Thus, '70 sales were shortened by four months. Hence, the '71 and the '72 Corvette were visual extensions (more or less) of '70. The '72 model was the last to have chrome bumpers, a removable rear window, and side front fender gills. Seen here is a new '73 with federal bumpers gracing the cover of Corvette News magazine, Chevrolet's in-house publication.
