I went thru this dilemma some 25+yrs ago. The stock Carby linkage rod is zigzag shape and the GT/pinto carb link is straight with a 90° into the fitting. I went thru books and wreckers which were filled with escorts Capri cortina at that time to pick and choose. Easiest way is to get a mk2 escort rod and bkt that bolts to the intake.... If you are unlucky and have a cortina gt intake without bkt mountings you'll need to adapt a bkt(plate to reach and be strong as not to flex) from the tin rocker cover or Ally weld a thick plate to the intake and thread it for the bkt ..I went the rocker cover way , my 1700 Kent had a pinto carb but later went to a 40dfav V6 carb . Hope this helps
