apparently a replacement might fit and might work as well however the calibration would be different.
like for a 2C engine full level oil mark is around 4 Litres of oil and for your ride its around 7.2 Litres of oil.
better would b to find a person in peshawar who knows pashto and can go to old kabli parts market (since they r the source to all markets in pakistan). once he finds the qabli replacement, get it with the warranty to keep it if it works.
(kabli parts have a saying associated to them, chalay to japan tak, na chalay tow sham tak) 
saving 35K by putting in the effort to find qabli replacement would be worth it i think.
besides another approach could be to take out ur current sensor. get it inspected and fixed. it might be repairable if its just a float type sensor.
