Portuguese AE86 with drum brakes in the back??

Yeah, I forgot to say, but it's a Levin. I was confused because it came with a 4AGE, some SR5 came with a 4A or 4 AC, but not 4AGE. So it's most likely that the previous owner did swap the engine, bit kept that brakes. Next time I have the chance to see it, I'll take a pic of the "VIN" number(I mean the metal plate, forgot it's name in English). I did took a pic of chasis code when I last saw it, do you know where or how I can check the differential code with the chassis number?
