Problem with replacement Idler Arm

You know that may be exactly what has happened. I cant get to the car to take a pic its 3 hours away from me. I will be heading up there again in about 2 weeks. I do remember when I bought the car the guy mentioned something about the calipers and brakes/rotors being from a '75 car. I thought that was strange. If that is the case and they did switch out the knuckles and all that, is it possible to just replace the center link with the correct '71 center link. The reason being is Im switching out the steering box to a manual steering from a '68 car, where the pitman arm stud faces up.

Knowing my luck its not just a simple switch and I will have to look at switching everything over.
