beatin' the dead horse again

the early a bodies v-8 centerlink is shorter than the later ones.....I made the same mistake putting my 63 together. bought a v-8 centerlink from a 72 dart and had to run my tie rods in to make it work. Found a brand new nos 63-66 on ebay and sized them up, sure enough they are different lengths. I can't remember where the extra length is added though.
