Ford used molded foam for the fastback rear seat, but not for coupe/convertible. What they used was a mesh-backed cotton batting.
We sell the proper stuff, matching the original in weight and thickness, enough for one rear seat.. NPD # 66800-1A . Cutting with strong, sharp shears is required.
We also sell padding kits for the seat frame edge (replaces the original jute and horsehair padding that Ford used on the edges of the seat frame sides), NPD # 63436-1BK .
Burlap set is NPD # 918-2 .
Rear seat listing rod set is NPD # 631A08-2A .
If you have any questions, or want some good tips, email our MI Manager Jeff Fein at
jfein@npdlink.com . Nights and weekends, all he does is professional upholstery installation. He's probably got more hands-on experience with installing Mustang upholstery than anyone in the world. I wouldn't be surprised if he hasn't reupholstered over 1,000 Mustang seats in his career. He's the one who researched and put together all of our upholstery installation supplies and gear, as the industry never really "helped" on the rear seats until Jeff fleshed-out that section of our catalog.
