We here at XenonZcar got in contact with a manufacture who has stepped up to reproduce many of the interior trim parts that are no longer available.
They consist of a thin, white, substrate to which a burl wood grain vinyl is overlayed. Then the white lettering is actually the exposed substrate after being routered. Each has a self-adhesive, peel off backing. You will have to carefully remove the overlay from your particular pieces and these go in their place. You can use “Goo Gone” or even WD-40 to remove the old adhesive.
There were two different bezel sizes on the Z31 depending on model year. Early years used a smaller rubber shift boot where later models used a simulated leather boot. Please be sure you are selecting the correct model year.
These Items have a 4-6 week manufacturing lead time.
