Has anyone seen this bolt head marking before? I only have like maybe 4 or 5 of them running around my engine compartment but I have not seen it before and I don't see it in AMK's, NPD's, or Virginia Mustang's catalogs. Also Charles, I looked at your blog on the K code convertible and didn't see it there since my car was built about 2 months before the convertible in San Jose. Do these bolts not belong or it just one of those one offs?
