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.
