I just talked with Don at the Bird Nest and he verified, As John said, that no one is making reproduction vinyl/cloth Trim Code 72, 73, 74 seat covers. He confirmed that SMS Auto Fabrics can sell you the material as they have tons of OEM/NOS seat cover material. He also said that he thinks they have now gotten to the point where they can sew the material for you and deliver completed seat covers. I just confirmed that with them. If you send them the old seat covers to use as a pattern, they can sew you a new set, front and back. The cost for that set will be $1,500-$1,600. If you just buy the material and have some professional interior guy sew seat covers for you will cost about $95 a yard for cloth material, and $55 a yard for vinyl. The total cost for both materials is about $600. Don said that SMS has been around a long time and is a very good company. Here is a link to their page where they show the Trim Code 72, 73, 74.
