what length bed are you looking to replace? i only ask b/c my brother had built a flat bed for a 150 that had a short bed. got rid of the truck. still has the flat bed about 6.5-7 foot long.
before i open my big mouth. i dont know if hes looking to get rid of it but he is not actually using it right now. if you are looking to replace something that had an eight foot bed it would be too short anyhow
