Well, if you want a safety device for the trailing arms, that shouldn't be a problem. You could mount a bracket onto the trailing arm, and a second onto the chassis. Then connect them both with some high tensile chain. The chain could be coated in either rubber, or plastic to keep it stiff, and from rattling when driving. Steel cable could also be a possibility, but would be a pain to strap into place. I'll be honest though. This seems to be overkill if you're going to install the improved bolts. But it is an idea if you want to go all the way in fool-proofing the bolt. -Robert vin 6585 "X" --- In dmcnews@xxxx, tobyp@xxxx wrote: <SNIP> > The second point I wanted to clarify is in regards to the subjects of "fail safety and structural redundancy".
