Best suggestion: get a brand new line from an auto parts store that's designed for your truck. Then compare it to other lines they've got there. As long as both fittings on each end are the same, you're good to go. Might be somewhat of a pain, it might not be. Might be as easy as a number changed on the part number alot like serpentine belt part numbers.
