This reproduction Corvette dash speaker mounting bracket is a new diecast replacement for the speaker mount under the upper dash pad of your 1970–1977 C3. Each bracket has three mounting points that attach to the underside of the upper dash pad and four pins for proper speaker attachment, restoring a solid, correct factory mount.
