I wil follow your thread with great interest and I can only confirm what generationx wrote : check your references ! I noticed no less than 6 body versions for the works (or semi-works) Escorts between 1975 and 1980 so you must absolutely know which version you will build first.
Moreover, if the rear arches of the Esci/Revell kit are close to the tarmac specs of circa 1980-81, the front arches are wrong for any version
