I have a Daystar Leveling kit that was on my 2005 F350 for about 4 months. I have the installation instructions and the pads are in excellent condition. Will fit F250 and F350's with coil springs. $50. plus shipping. I'm in SW MO.
They are photos on Spfld MO Craigslist right now. Just do a search on auto parts. They are 2 or 2 1/2 inch rubber blocks that go between your present coils springs and the upper spring mount on the frame.Do you have a pic of the leveling kit
