Wow...good thing that u r making the videos>
some points:
Save the plastic air vents pipes as they are hard to find and must be very brittle and can be easily broken
Save the air box, clean it, seal it and re used it as it will help u to install the ac/heater in the car.
Get rid of old wiring and buy new suzuki mehran wiring loop with complete fuse box. This will save u from hassle of connecting old wires with new wires, changing connectors, holders and all.
Save the tray beneath dashboard as this is also a rare item now,
I can see that the front seats are changed and from some japanese car. thats a great thing.
The back seat has been supported by a metal pipe. ask ur dentar to resolve the problem
change that bloody steering and get a good after market one if u dont have the original.
While doing the roof, ask ur dentar to support the roof with khyber/alro roof patti inside as per attached picture
