Hello GMC Nuts,
Hang tight you 58-59 GMCers... full-blown perfect looking replicas of the 58-59 GMC park lamp bezel, bracket & cone lens will be offered soon. They are about 80% done of the final stage, just need to apply the mirrored silvered finish on the backside of the plastic bezels. The replacement cone shape lenses are exactly perfect to an NOS lens, even has the small wording that say CATS EYE No 85! I'm not the one reproducing these lights... but I will be purchasing a set for sure!!
Here are a few photos to drool over....
