1967 Barracuda Fastback Interior options?

As a upholstery shop owner I would say use legendary.
I installed a lot of seat covers of I believe all the brands and they have what I think is the best workmanship and materials going that I have found when it comes to our mopars.
I have had to do almost no repairs on their products to get them to show quality.
No one is perfect. But in my opinion do yourself , your car, and your trim shop a big big favor and give them a try. You will be happy with the results.
I have only had one set of covers from them that wasn't up to their usual standards.
It was a material problem not workmanship. It was on a pearl white vinyl that I would guess they had difficulty sourcing.
