Are you building a Cosworth? The Escort MkV platform (and Mark III Orion saloon) arrived in September 1990 with an all-new bodyshell and a simplified torsion beam rear suspension (instead of the Mark III's fully independent layout). But if its the cosworth car you are looking at, then the model released over there should be identical (unless the ones i've seen over there are imports) and of course aslong as it's not like the focus which is different in the States a they seem to have a shorter 3 door version.
