First of all, congratulations on buying Khyber and encouraging your interest in restoring it. Your car is not in such bad condition as I was expected being Karachi car
Sort all tasks work-wise.
Denting & Painting:
Give to some sensible denter painter to scrapped chipped old residues of paint, then repair or replace most rusted parts. Better to change complete floor, Do proper anti-rust treatment and Tell them to change the color of the car.
As engine will be seated off away from engine bay, so do remaining work in parallel.
Mechanical: Engine Rebuilt but you have to bring it to Factory settings indirectly means you have to return it to optimal state.
(i) Overhaul carburetor completely or if not possible in your city, then replace it with new Carburetor of Old Cultus(2000-2016) or Mehran Carby. Model.
Mehran new carburetor is around 13,000 to 15,000 while Cultus carb. is around 22-24K, both will work, prefer Cultus carb.
(ii) Connect all vacuum pipes
(III) Install new water body and service your radiator. Replace your Flynge
(iv) Fill your radiator with Toyota or Zic coolant
(v) If there will be no leakage or heating issue, Then install T-stat and finally make your fan automatic
Electrical:
Wiring is messed up. Complete re-wiring work required, install Relay boxes, Fuse boxes from any jdm car.
Install EPS for smooth power steering
Then install/fix A/C to cope with summer hot days.
Tyres & Rims:
Install 13" Rims with new tyres of profile 175/70R13
Finally Interior:
When electrical and mechanical works get sorted, then make seat work upholstery, new foaming, door cards, roof.
Repair Dashboard.
Install power windows
Install central Locking Steelmate security system
Install speakers, good music system
MOST IMPORTANT...DO IT TODAY
Your car documentation is not good. Do it correct Legally ASAP. Your car's MVT (Motor vehicle tax) is not paid since last 7+ years. Car is on some Riaz Shahid Name. This is serious crime and illegal to keep and drive car on Open Letter and do not paying taxes to Government. Pay tax and Transfer properly it on your father's name immediately.
If you need any assistance or work from Karachi, you can contact any Karachi's pakwheeler to help and guide you like if you want to do dashboard repairing, send via Daewoo cargo. We will repair it, wrap it from here and send back to you via daewoo Cargo or similar bus cargo service.
