I have tried just about everywhere to find the factory seat cover for my '58. The back section of the seat still has the original cover but is a little worn. Looking it up in the dealers manual it is described as "Silver and Charcoal" and has a a rectangular "brick" pattern in the charcoal area (1" x 3/8"). The silver is on the sides and the charcoal is on the seat area with some wrap over. Fellow bolters, you have always been a big help in the past, hoping you can be there for me again
