Better if install original ones but check your chassis & current axle from some professional suspension maker. In which city are you located?
@haris.etilize
In your case, i had similar case in 1 of my Khyber perhaps in 1994 when our Khyber 1993 got accident from front badly and Chassis was bent too with major effects to engine bay, suspension system etc.
At that time, i gave my car to Denter uncle near our home, he repaired chassis without any alignment machine or chassis aligner, just by Hathora & Feeta (meter tape used by Tailors for measurement of waist)
When car was ready, original axle parts were provided by us but just running after 1 day, axle star broke, when we repaired it then after 20 minutes drive axle broke, we fixed it.
Car was badly pulling towards passenger side.
Next day we went for wheel balancing & alignment, after alignment during test drive, alignment issue got fixed but again that axle star broke.
Then we went to proper axle wala in Nazimabad who did measurement and put customized axle rod just like your car(in which 1 side was relatively longer than other), after that issue was resolved to much extent and no suspension problem appeared again till 1999 when i sold it
