Your obviously well clued up on them then, 100% correct!
The box however was replaced in 99/2000 i think with the later type. He had some parts to put on it like Tipo 16v brakes etc but never got around to it, should have added at the start, one of the main reasons for the car being locked away was that it was vandalised/attempted theft, hence the dent on the drivers wing.
Brother got a knock on his door one day by a traffic warden to tell him he "couldn't leave his car in the road like that" he had no idea what the guy was on about, so went and found the car with no windows and wheels just lying in the road, they hadn't even bothered leaving it on bricks...
Anyway insurance company wanted to right the car off just because the windows were smashed and the wheels stolen, so he fixed it and put the old wheels on and put it in the garage.
