I wished I had some of those straps. Instead I looped nylon webbing around the axles and subframe and tried to twist-tighten it with wrenches. That didn't work so I trimmed about 3/16" off the fronts of the bushings. I also took about 2 mm off the diameter of the re-usable steel cups so they would move freely backward. What a nightmare. I had the diff in and out of position 4 times.
