There are a number of upholstery shops who are capable of recreating a 1955 Caribbean interior. SMS and others offer similar leather. The original leather is much thicker that most of the samples today. Additionally there is the challenge of the clear/silver piping around the front seat frame seat. Bolsters also need to be built up on the seat cushions. The great news is that there are lots of photos on this website and other places that a good trim shop can use to recreate a beautiful interior.
