Anybody know where I could find one that fits and matches the grey-silver interior?

Mine Doesnt work.

You don't have to purchase 1 from them, but go to crutchfield.com. You can put in what kind of car you have, and they will tell you what fits, and what won't. The color, that is your preference. They sell the full install kit, and all the wiring harness. If you do buy tunes from them, i think they will throw that in for free. I purchased a Pioneer stereo from them a few years ago. Looks good in the car, and it works fine.

You won't find a new one that matches the OEM one. the OEM one is non-standard size. But as said above, you can find a new 1 DIN stereo as long as you get the new face plate/mounting bracket. However, it may not match the AC/Heater face plate. My face plates were silver and the new radio face plate was black, so I covered them both with real carbon fiber sheets so they would match. You can also try to find an original one from someone parting out their Z but the OEM radio is a piece of crap and I would recommend geting a new modern one.

dooood i want the chrome 300zx....did u make that?
