The chassis side rails should be straight, but many cars have ben overloaded and abused over their years of existence, and I have seen chassis with a slight sag in their length. With care and persistence straightening is possible using small RSJ sections with spacing blocks and clamps. In practice the side rails need to be pulled marginally past straight because they will spring back when the clamps are released. After doing this correctly I think the steering column will settle in the right place without problem. The only time I did this chassis straightening I also welded square hollow section into the chassis to strengthen it and avoid future problems.
