Thanks that helps out a lot. So its the same with console and instrument panel too all interchanges. And radio bezel
Console: the console needs to match the dashboard. A 97-02 console won't fit properly with a 93-96 dash, and vise versa. Colors are also different by year.
Instrument cluster: 93-96 have a mechanical odometer, 98 has an electronic odometer but different pinout than the 99-02 electronic odometer. You can only replace the instrument cluster within the year ranges posted... i.e. 93-96 can only be replaced by 93-96... 98 will not work for a 96 and neither will 99-02. Why would you replace it anyway? Just get a gauge overlay from 6LE Designs or Black Cat Custom Automotive if you want it to look different.
Radio bezel: 93-96 will interchange with 93-96. 97-02 will interchange with 97-02. There were a bunch of different shades of gray though so unless you are sure it is from the same year as the rest of the dashboard, the color will not match. Dashboards are the same as far as interchange goes, and when you change dashboards you will need to change the expensive dashboard upper panel too along with the HVAC switch and possibly the headlight switches.
Are the basic model interior parts different than as z28 or ss
Aside from material options when the car was purchased (leather interior vs. cloth, special edition or normal), and the little plastic emblem insert on the radio bezel, no.
