In Khaled Hosseini's novel The Kite Runner, Amir's narration skips forward several years between Chapters 9 and 10. Chapter 10 takes place in March of 1981, a period of time during which Russia had invaded Afghanistan, resulting in intense international conflict.
Amir and Baba are riding in the "tarpaulin-covered cab of an old Russian truck" at the beginning of the chapter, being smuggled over the border in order to escape possible retribution from the incoming armies and government.
Unfortunately, the exact make and model of the truck is never stated in the chapter, possibly because Amir did not know these details. I have attached two possible resources for further investigation: each is a list of Russian trucks produced over the course of several years preceding when this chapter was meant to take place.
