Granada Scorpio Hubs Part #'s

[AndreasW]

Hello,
can anyone help me to get information on these spare part numbers below?
I would have to know whether these are four or five stud hubs.

6816786+6816784
6542128+6542121

Even better would be the drawings of the numbers.
Does anyone have access to a Ford spare parts catalog?
On the net there is only little information.

Thanks
