how do i make my 1990 skyline gtr dot approved

well if u have to - day time runners with dot dot standard head lights - no leaks of any sort - and a inspection to get it approved they will go over on what u need to get it approved

Or wait until it is 25 yrs old and can register it as a classic. My R32 GT-R is a 92, so waiting until 2017 to ship it over from Germany.
