that's seriously not the issue. if you look at the those pictures of the 737 frame - this is very large system which hasn't operated for many years and is largely just a pile of components at this point. it would probably be easier to rebuild the control system from scratch than try to bring it back to life. this would probably take a team of pretty serious people many years to get functional.
