I purchased my '73 vert about six months ago and both doors were out of alignment. I'd taken it to several body shops to see about getting them aligned. At the body shop I took it to today the owner told me that he's seen this with many convertibles (I hope I'm able to explain this accurately); he says that the subframe rails have flexed over the years due to there not having the additional support of the roof; therefore, the car is bowing down to some degree, causing the doors to be misaligned. Does this sound possible? He says that the proper procedure to resolve this is major surgery involving the cutting and removal of the old rails and the installation of new ones, which means gutting the interior. This could run $8,0000-$12,000. Now, please believe when I say that he wasn't trying to sell me on such a procedure; his is a very busy shop and he's not attempting to talk me into it. He did, however, say that there is a much cheaper alternative which involves jacking up the center portion of the car until the doors are aligned, then bolting and tacking in new subframe connectors. He said that's about a $1,500 procedure but that he personally wouldn't do it - that it's not the proper way to go. What are you thoughts about this?
