I'm going off my memory, scary! OK what I did was drop tank, look at the inside frame side of hanger, there is a protruding stamped piece with a weld all around the 1" rod that goes all the way from the outside of the spring with the threads to the back side to the end of that stamped bulbous piece. Take a 4" grinder and grind around the weld of the 1" rod till you have a pretty good guide to use hole saw without the pilot bit. This will cut the rest of the weld without loosing any of the length of the rod (for future welding in new location). Remove bulbous stamped piece (after rivits are removed) then you eill discover a 1?8" plate with two vertical welds holding it on to the frame, carefully take same grinder to those welds. Remove that plate, at this point everything will be off the frame. Flip that plate around and insert two bolts. Mark where the big hole goes and get that hole in frame. Then re-install everything flipped. I remember trimming the bulbous stamped piece to clear something, I think it will be appearant when your there. Get two bolts in and tight and match ream the holes. Bolt those in and youre good there. Lastly re weld the end of the boulbous stamped piece back to the 1" rod.
