Hank, Looks to me that those torsion bar female recepticles are WAY OUT of any acceptable tolerance. I would say you are really close to wearing that door for a hat! Yes, get it fixed. Pronto. Unless it's on the wife's side of the car...then don't worry about it! (kidding) Be VERY CAREFUL replacing them as the stored energy within the torsion bar is incredible and can easily injure you or even worse, seriously damage your car! There is a published detailed proceedure for this at a couple of the DMC sites. This is one is pretty good: http://labwww.csv.cmich.edu/luke/auto/delorean/repair/default.html I have done this twice using this guideline and I am still alive! This site can also answer your other questions regarding the tires and other specs. As for that connector, it looks like that little nasty bugger that plugs into the warning chime located just above the steering column near the fire-wall. I guess the former owner just got sick of listening to it! Good Luck Sal
