That was the 17th last Sunny to be made... and 5th last RHD model (and although black was the most common colour, it is 1 of 38 black RHD).
Nissan have discontinued the body panels. You can get aftermarket replacement front wings/fenders, and you can use part of the 4/5 door rear panels, but that's about it.
Thanks for the info, yes 20598 is the car im rebuilding. I have owned it since 2001 but due to me working in South Africa it has been wasting away for the last 15yrs.
