Need upholstery help!

[bigdon-70blazer]

I am getting primed up to re-upholster the 1970 Blazer seats. They are the plain jane utility buckets and rear seat. I understand that the plain jane vinyl covers that they came with are not being reproduced and the same material for the bench seat trucks is also not being reproduced so I could not buy bench seat stuff and fashion it into what I needed. That is true, isn't it? Please let me know. My next step would be to get something as close to what was original and get that fashioned into fairly close looking seat covers. Anyone with upholstery experience chime right in. I want to perserve as much of an original stock look as possible so I will want to perserve as much of the original lines as possible. Please help, any vendors or upholsterers please assist me in the quest! Thanks
