I'm a little lost JHerrlich... . if you noticed in the TSB, you don't put the bolts over the straps, you pound the straps onto the heads of the bolts to hold them from spinning. It looks to me like when they were first put on my truck they put them on too far, and it caused the straps to become to loose, allowing them to fall off.
Don't know if this answers the question or not, but maybe.
