James - The best way to get the full story on most technical issues with the DeLorean, including the trailing arm bolt issue, is to go to the technical library at http://www.dmcnews.com/techmain.htm and click on the desired subject. I wrote a series of pieces on the trailing arm bolts in the section entitled "Trailing Arm Bolt - Engineering" within the "Suspension and Steering" section. As you will see, there is a great deal of information available through this area. If you read these articles, and still have specific questions, you can post them to the List, or email me or one of the experts that frequent the List. I hope that this helps.
