thanks arid and kiyani1.
i have noted down the prices which you have mentioned. i purchased side fender it costed me 300, it would be desi type but the whole mehran is desi one 
got new both bumpers and both pairs of lights including grill, now going to get new locks, rubbers for frames all over it.
what about new steering how much will that cost?
need to get channels for all windows.
i have asked the denter to clean the whole thing scratch out all paint and then show us the metal.after that he will apply paint. what do u suggest?
