Attached are a few pictures of my original tie rod sleeves. They were a natural finish. I replaced my rusty nuts and bolts with black oxide plated bolts, and silver cadmium plated hex lock nuts shown, from AMK Products.
I would like to confirm what the original bolt head markings were for this application. If you still have the original bolts and nuts on your '69 tie rods, please post pictures and let us know the build date and VIN of your Camaro.
This will help to identify points in time when the Norwood or Los Angeles assembly plants may have utilized the same supplier’s nuts and bolts, or show that hardware from various suppliers was used.
