Steel 1966-1980 Small Block 327 and 350 Corvette exhaust manifold French Locks.
These thin steel retainers are used to "lock" the exhaust manifold bolts to keep them from backing off. Tabs are folded over to prevent bolt from turning.
Located on the front and rear bolt positions when installed.
Note: At Mid America Motorworks, we call these parts FTF, or Final Touch Fasteners. When you’ve spent countless hours of work, worry and detail, we don’t’ want you to lose that final assembly look by using incorrect, rusted or mismatched fasteners. From correct finish, to headmarks to fastener design, we endeavor to have the Restoration Correct Fasteners to add that Final Touch to your Corvette Restoration Project..
