Which ones, all of them? Link is for a 65-66, this is 67-68 ...
Believe most of them were phosphate and oil, but without more clarity not sure what items you are referring to.
If you meant the allen head set screws with ring/washer, they are not reproduced as far as I could find a while back. The rest of the hardware, if not exact is available from AMK in "very close"
