Restorers: Did your body metal parts assemble easily?

[Sunnybrook Farm]

Much of it comes down to the frame and how years of flexing in various directions causes the bolt holes all over the car to be slightly off even after a restoration. Then consider that the body parts are stretched and patched as well. Even if the frame were riveted again there might be some bend in the steel. It is hard to make it like new after 85+ years.
