Joe, With due respect you most of the time disagree with me. So what's new. The testing you do or the factory did was for a short time. I'm talking about fatigue over time and weather conditions. Constant pulling, stretching, and jerking, not just popping the clutch a few times and I pronounce you good, lets talk about it over years and maybe one, or two clutches later. Come on, You can go have a heart check up tomorrow and every doctor says your OK, then drop dead tomorrow. Everybody knows someone this has happened to. I agree, with you and relinquish to your time of working on the De Lorean that the trailing arm bolt it probably a mute point, But, I think to the folks up north who have to worry about salt spray and rusting it's more of a pronounced problem. I hope Toby can come up with a reasonable priced bolt to help ease the mind of some. But I to have worked on cars all my life also and do know a little. The Delorean is a car not a God and a bolt is a bolt. You can't test something for a short period of time and pronounce it good. Why do you think the military went to a salt spray test and most mechanical parts failed in the late 70's and eighty's, they found the conventional testing wasn't sufficient? Race car drivers spend $1000.00's and still have a bolt failure. Thanks for your comments, I always enjoy the exchange. By the way, have you shipped my parts yet.
