Depending on the year of your Blazer, it could be either a full-size SUV or a compact/mid-size SUV. The earliest Blazer models were produced in 1969 and sold through 1974, and were later named K5 Blazer. The Blazer nameplate was brought back and attached to Chevrolet's full-size SUV in 1987 and sold through 1994 until being renamed Tahoe. Up to 1992, the Chevy Blazer was built with a removable hardtop shell that essentially made the truck a convertible. This didn't really serve any functional purpose, as the entire cab was opened up. But it still looked cool. 1995 and later Blazer models were all compact/mid-size SUV's. These were smaller than the full-size Blazers, and were based on Chevrolet's S10 pickup rather than the C/K. You'll find that a great deal of Chevrolet Blazer parts are the same as those found on the truck that shares its platform.
