the long discontinued model cars parts are available mostly in used cars parts markets like bilal gunj, sultan ka kho etc. .. they are mostly scrap imported / stolen parts : /
it's a news for me that toyota still sell 1974 model car parts at their dealerships 
the problem with Khyber is that the international model of it was discontinued back in the 80s and that too it was not produced internationally at a global scale, hence there no parts of it available even in the international scrapyards, thus the old Suzuki models suffer greatly in this aspect..
the models that were hit globally, like Swift, have used car parts in abundance..
but still...the supply chain problem in itself is true , should've been better .. like Toyota is delivering their assembled cars faster than others in the market due to streamlined supply chain management.
