ZSPEC "Clock Delete" Plates are Anodized Black and are designed for the Nissan Z32 300zx. The 300zx Z32 clocks often fail and owners have clocks on their aftermarket stereos anyway...
Here's a simple idea an enthusiast brought to us and we ran with it.
The plates are anodized black and available in these styles:
Fairlady Z laser-engraved
TWIN TURBO laser-engraved
