I didn't know the name of the vertical stripe patern '81 only material. As for finding it. I would keep my eyes open on ebay. I have a '81 blue turbo car tucked away for my planned museum and was lucky enough to find considerable yardage of NOS correct blue strip material for this car. Wether or not, '81 material will be reproduced or not, I don't know.
