Thanks for quick replies.
Jasper, the top joint is from a Transit I know so maybe you are right.
Dave, it doesn't look like the Maxi but suspiciously like the Cortina one. The Granada one also is exactly the same style as the Cortina pictured but the distance from the two holes on the left to the holes on the right is shorter than on the GTD item.
I need to get a helpful person in Partco or similar. But nowadays they seem to want the make, model, year and even registration number to identify stuff.
