In attempting to install new rear hatch struts in my 300TD, I have run into a big problem.  I got one strut out, but could not seem to line up the bolt under the headliner with the strut and its receiving hole.  I could get it into the opening of the strut, but I could not seem to get it threaded.  Now, after looking at it carefully, I think that the first ring of threads may be cross threaded--with the strut out of the car, I can start the bolt, but only turn it a few times before it gets really tight, so of course I backed off.  
Anyone with knowledge of how to fix a possibly stipped thread in this inconvenient place, please advise.  Also, anyone who has a secret for getting the strut lined up correctly and getting the bolt through, then attaching the collar to the hinge, please let me know.  Thanks.
