You can get any Toyota part from Al-Futtaim provided you have the item code or whatever its called.
There wasn't a GCC spec Supra, if Al-Futtaim did sell Supras (which I'm almost 100% sure they did not), they must've been USDM. Toyota never produced a specialised 'GCCDM' Supra.
BTW, I'm guessing you are from UB?
