Trying to figure out if this is a zinc bolt or phosphated?
Mine appears to be a L5 on head and dark. Maybe zinc is gone??

bill, I thought the bolt was bare steel....could be wrong
-
Only speaking for '67 L35, especially the unrestored one, they are phosphate.
I can't recall ever seeing bright zinc bolt on first gen's.

Mine is a phosphated Grade 5 (3 lines) bolt with traces of orange overspray (02D '69 Z/28).
