I assume you mean to have the seats reupholstered. If thats the idea, you may want to go to an auto upholstery shop and just look through the available fabrics.......there seem to be thousands of them....... and pick one. For the door panels, first check the bottom edge. Often it disintegrates over many years from moisture getting inside the door cavity. I used sheets of 1/8" thick flexible plastic sheet (it was surprisingly expensive) marked off the shape, cutouts, holes for mounting clips and cut to size. Then I used matching fabric, which the upholstery shop supplied, thin foam sheet and 3M spray glue to make up new panels. Its not stock but similar to original.
