I recently pulled the interior out of my 84 300ZX Turbo to improve the stereo system and to try to resolve many of the noise problems you mentioned. I used the Dynamat sound deadening (stick on) material on all exposed metal surfaces after removing all interior panels and carpeting. I also applied 1/8" or 1/4" thick Felt carpet padding on door panels and under the carpets. You can use spray adhesive or good double backed carpet tape to apply the padding. To address the squeeking panel problem try the following methods: 1.) Make sure all the panels are really clean before reassembly. Final clean mating panels with rubbing alcohol. A little dirt can make alot of noise when rubbed together. 2.) Glossey surfaces have a tendency to stick together and squeek. Try some light sandpaper on the touching surfaces. This will cause the surfaces to slide without squeeking. 3.) Saddle Soap. That's right. Saddle Soap. It is not just for leather cleaning. Soap never really dries out and will act as a lubricating film between the surfaces. It takes alot of work to cover all the interior surfaces to resolve noise problems. However it will be worth it. My 300Zx Turbo is as quiet (or better) than a new car. Other 300ZX owners are amazed at how quiet my car is and at how good the sound system is. If I can be of more help e-mail me at: pcd_2000@yahoo.com. Good Luck. WiZZard

I'm not sure you can change the display without involving the reprogramming an EPROM or such. Sorry I can't be of more assistance. WiZZard
