Thomas Bechholds is who I have been dealing with. Very helpful and answered all my questions.
He said that 3.5 meters should be enough to do the front and rear seats of my 1980.
He also set me a sample of the material and it is dead on. I will probably order some time next week. It is not cheap with the shipping, insurance etc, but it is top quality and it is not outrageous either.
I was quoted $448.00
Thomas seems to have all the sought after interior cloth's. Top quality.
