from what i understand it is NOT required to cut the hard lines....I am all about saving time and dont want them so taking the easier route. My buddy is wanting to check the pump and something else for his shop as spare parts....and another guy wants the actuators if they are any good still. Not sure much need for hard lines unless you may return it to your rig at later date. My experience is that other than 3rd row seats.....these trucks rarely if ever get de-modified. I think I have read of one person out of thousands in the past 20 years.
