This car has long history and many owners. If we go far backwards... In some point the original rear lights and some other parts were stolen. I don´t really know that person who built this car before, but i´ve heard something.
(stripped bumpers, fitted new lights and exhaust, 1st rust removal, red paint and much more)
I´m pretty sure that previous car builder didn´t even know what is Nissan Skyline, and the model was something like Ferrari...
I have now original USA rear lights but I probably change those to Euro model.
