i appreciate the advice - more than you know - 
  
I told him to jack at the pich wield - but he said he knew waht he was doing - 
and then he bends it - 
  
i think he would have done more damage if he had continued - his intent was to cawl under the car 
so i stoped his job and decided to have it towed to a shop to be worked on - 
i guess it is possible the car could have fallen on him 
  
he did not break the metal - it's like he bent in the sqaure shape rail at the bottom - bent it out of shape with the end of his jack - 
it looked like the jack was bending the hollow rail before it could even lift the car 
  
I do not see any rust in this area - even after the bend 
i have no idea how to inspect inside the rail 
  
after this incident I looked under the car on the other side and I did notice a rust spot at the end of the other rail on the passenger's side near the rear - 
so maybe  water has collected inside to of these sqaure rails over time 
  
  
I have a rust problem at the rear of the car from tailpipe exhaust over the years 
  
I'd like to find a good way to stop this rust - but I think I going to need a rear panel around the lisence plate 
  
If at some point the rails need to be replaced -- is there some source on this 
that someone can recommend - 
  
i have a 280zx 83 coup - orginal owner - 
130,000 miles 
it needs body work and new paint job
