As your car was a Ghia with a 2ltr, it should have the Aussie 2L struts in it. The diameter of the tube is 51mm I think. Shouldn't be too hard to find but if you have any dramas I have a few kicking around here. Let me know how you go.
Also, when you get new wheelbearings, don't settle for the chinese rubbish that the parts suppliers give you. Tell them you want a bearing that is made in Japan.
Cheers, Craig.
