I just had my plastic dash bezel for my '67 427 Comet redone by CV Vacuum Platers in British Columbia, canada phone # 604-820-9571,

An absolute "work of art", perfect job, fairly priced, 6-8 weeks. They plate and do all the silkscreen blackout, silverout, etc. Nicer than NOS. Don't look any further, they are the source.
