I have a question,
The european name for the cortina is a taunus, but do the taunus and the granada have the same uprights ? and if is it possible to exchance the hubs?

because i can't find a taunus on the schrapyeards only 1 granada.
the uprights looks like one from a taunus/ cortina but has a hub with 5 studs.

so please give me some advice becaus i don't like the sierra uprights.

i've always believed this is possible but i've never seen any proof.

Suppose the easy thing to do is see if the bearings are the same for both. If they aren't then checking if the ID of the bearings is the same will give you an indication.
