71 duster front end help

Ok i rebuilt the entire front brakes and suspension on my duster using a disc brake conversion kit from Dr Diff/ The right stuff detailing. I bought all new upper control arm assembly from him as well. The steering center link and box are factory, the idler arm, pitman arm, and inner / outer tie rod ends plus sleeves are Moog.

I marked everything as i took it off, the problem i am having is the 2 tie rod assemblies are not the same length now? the stock ones were 12.5" grease nipple to grease nipple. When i try to set the new assemblies up that way, the drivers side it good but the pass side needs to be 13.5" long in order to get the rotor straight.

I made sure the master spline on the steering box and coupler were lined up. there is no way it would go on any other way. When i turn the steering wheel inside the car, it goes aprox 1/2" more to the drivers side than the pass side. Should i try to center the box to make the tie rods even, then pull the steering wheel and re line it up? Any help would be great.
