SMS supplies about all the upholstery for the different companies that do interiors. When I did my 61 I used Labarron Bonney. They get their upholstery from SMS. I waited over a year because they couldn't get one of the pieces in the correct grain. SMS couldn't tell them when they would have it and didn't really care. I finally settled on upholstery with a little different grain. You can tell if you look at them side by side but in the car it looks just fine. So if they tell they don't have a certain upholstery be ready for a long wait.
