Here is a previous reply from Mike to an enquiry from James.
Hi James,
Without taking the car apart here is the best I can come up with. I have measured the holes in the hub carrier which hold the carrier to the upright. They measure 10.63mm 0.419". According to my Zeus thread chart the clearance hole for 10mm bolts is 10.2mm. However the Ford bolts seem to have a thicker part of the bolt shank to centralise them.
Many of these parts for Granada Mk3/Scorpio are getting a bit rare but many are common to the Sierra. Look for breakers on Ebay or locally but they are thin on the ground now.

You could ask them if they are suitable or indeed what the thread size is.
If I remember correctly they have a sort of sticky blue Ford thread lock gunk on them.
As an aside the big nuts which hold the hubs together are handed and must be replaced with new if removed as the they are a kind of nylock nut. They also need to be tightened very tight to 200 ft lbs which can only be done with the wheel on the ground. I use a big 3/4" torque wrench to do this. I will look up the nut and socket size if you need it.
Cheers
Mike
Typical response from a very generous guy and a long time supporter of this forum who has been a great help to me over the past year and to many others for a lot longer.
It's obvious you don't know Mike Pass but I believe an apology would be in order.
Bob.
