I have a 1965 Mustang Convertible that I am in the process of restoring. The car is drivable, and I do drive it once or twice a month. The most recent problem that has surfaced is that I am having difficulty in getting the doors to latch properly, especially the driver’s side. I have replaced the upper and lower hinges, but this did not solve the issue. I have also lubricated the latching mechanism on the door, and that has not completely solved the problem. I have asked around to see about getting it on a frame machine so I can see if the frame/unibody are out of alignment, but I am having difficulty in finding someone who does work other than insurance work. It was suggested to me that I may want to consider having a crossmember welded onto the frame to “stiffen” it up. I guess I am looking for suggestions as to how I can begin to solve the issue that I am having with my doors not latching properly.
