4 stud on a Scorpio ?

I'd have thought any Granada related stuff was 5 ? easily drilled to 4 though. For such a light car...hard to imagine a need for vented, and it also requires suitable calipers which are getting harder to find unless using aftermarket

Does the OP have any parts at all ?

searching online catalogues you can find stuff
