NSX-R Type Rear Diffuser

[NSX-Wes]

I have been searching this forum and others for a rear diffuser that looks like the NSX-R. Does anyone know whether it is a bolt on for the pre-02 vehicles? I really love every part of the original design (especially the front pop-up lights) except the exhaust surround. It really looks outdated. I want to keep my baby factory original so anything I add on I will want to remove and replace with the original prior to selling.

I think I saw several of these a few years ago, but cannot find anything now. Any advice will be appreciated. I apologise if this is all old hat - just refer me to right place to read.

Thanks for listening,
Wes
