On the attached parts book scans -
54 = 4dr sedan, 62 = 2dr sedan, 78 = van
67cid = 1100, 79cid = 1300, 95cid = twin cam
The parts list shows all Mk1's sedans and vans used english axles up to 8/71.
All sedans and vans (exc. twin cam) after 8/71 used what I believe is an Australian made Borg Warner axle.
The Mk1 microfiche parts list shows all Mk1's from 70 to 75 use the same bearing part No. AUB24.
All Australian Mk2 Escorts used english axles and the microfiche list shows them all also using bearing AUB24.
