I think you have done an excellant job of research on the TAB. The Delorean community couldn't afford to spend $$$ on this kind of expertise but we can all appreciate the effort. I think your bolts are well worth installing for anyone who has any doubts about the bolts they currently have installed or the "pedegree" of any they might purchess. One comment I must include. If your TAB is bent then your thrust angle (rear alignment) is OFF. You cannot have the wheel pointed in the right direction if the bolt is bent. Once a bolt bends it is now WEAKER than it was and a lower level of stress could now fracture it. If the stress was high enough to bend it in the first place it isn't too hard to consider that it could happen again but this time it snaps. Perhaps we should consider these old bolts "time lifed" at 10 years or some other # and just issue a volontary recall? There could also be an annual inspection of the bolts for corrosion and bending added to the normal inspection and maintaince. In aircraft when there is a critical fastener ( and there are many) they inspect them and replace them at so many hours of operation.
