Hello Ryan,will be a bit harder to find a 3 door kit on the island i expect.
I saw a couple Sapphire Cosworth's in Bugibba last year
Perhaps if you ask around at the drag strip near the airport, someone might be able to point you towards some parts or a part finished project.
There's another user on here from Malta that had a Sapphire Cosworth which he sold to make way for a Mitsubishi Evo i think. He might be able to help you !!
