Nurburgring Sport Seat basket weave
I bought this about 10 years ago for a 356 project I wound up selling. It has been sitting in my garage ever since. Black leatherette basket weave material. Complete with slider.
One small rub in the material under the front lip (see photos)
Yes, it has the slot for the submarine belt.
You will need to get the mounting bracket.
It is in Denver but I am going to Los Angeles March 20th for the week and can take it with me. I will not ship.
