1956-1958 C1 Rear Body Mount Reinforcement RH 3770462 - OEM Number(s) (3770462)
Restore Frame-to-Body Strength Behind the Door
This 1956–1958 Corvette Right Rear Body Mount Reinforcement plays a vital role in securing your Corvette body to the frame. Positioned just below the passenger-side door striker, this heavy-duty plate was originally riveted to the fiberglass underbody and acted as the contact point for the rear body mount.
Decades of corrosion or previous repairs often leave this plate compromised—or missing altogether. Our exact reproduction restores factory strength, alignment, and appearance to your early C1’s mounting structure.
