your jeep is an 87, right? you will probably have a very hard time finding a vin decoder that works because jeep changed hands so much and mopar didn't start keeping track till the tj era.
and, couple that with yours being not a us spec, i bet you cannot find anything on it.
i tried a few and they all said invalid vin. i had similar issues on my 87 wrangler but at least it would say 87 jeep wrangler, just nothing else
this one at least shows it as a jeep
goodcar.com
that one found 87 cherokee but had a picture of a full size Cherokee
