On the fill side (driver's side), there are two bolts that are a loop that go down through the frame. On the passenger side, the original straps have j bolts on the ends the go up in the frame holes. The bolts and J bolts go through the spacers between the tank and the frame as you picture. Mine had some insulation/isolator, almost like a fire hose material between the frame and the spacer if I remember correctly. I took a photo of the set up when I pulled the old tank but I can not find it on my phone or computer.
