Can we use the streering column of a MK2 escort or does it have to be the collaspable Sierra type?

best bet would be to read the sva manual yourself, there was some dispute recently about if a 30 degree angle in the links was enough for SVA by itself or if you need the collapsable bit too. Cant remember how it boiled out myself.

Why not combine the 30 degree angles with a collapsible boss? Oli.
