Body Dampener Mounting
Short answer: The rear shakers bolt to the rail at the bottom edge of the trunk gutter (if there’s no welded nut on the shaker, they lay against the rail on the opening side). If they don’t line up, check the trunk floor for rust swelling.
Per the 1967 Firebird Service Manual (fig. 2-3), the 1967 rear dampener differs from the 1968: the 1968 has two top mounting tabs that point up above the dampener and bolt to the rail; the 1967 has a single tab off the side near the top that bolts to the vertical quarter-panel brace near the back of the trunk. Originals are mostly semigloss black with trunk-spatter overspray on one side.
