buickman, why do have have to box in the rear trail arms? didnt think you would have to modify a factory setup. Have you had engineers on a TE cortina?
A friend of mine use to work for ford in the late 60's, early 70's and ford actually tested a V8 in the TC-TD cortina. Problem was the clevo was to heavy for the cortina's light pommy designed front end. If the windsor was available at the time it may have been a reality.
