@ nadir Well it all depends on how much the pillars are damaged. Anything is possible in pakistan bro pillars kya cheez hai. But the question is that will it be strong enuff or would the lines be straight after the work has been done.
Similar case is with doors and fender u can always get them repaired but u can never get the original lines back, and with a freash coat of paint u need the original line of the car to make it look classy. Even on my 82 landcruiser i changed every body part with a dent just to get the lines right. Bro lines matter go for a body change.But do keep in mind at the current time bcs of the border issues u wont be able to get hold of a neat body and if it is neat u would be paying a lot for it. According to my sources u need to wait a couple of months b4 the border tension reduces and prices come down. As if u spend a lot of money right now when u do plan to sell it will still fetch u the same amount which these kinda car normally do.
Hope this helps.
