alignment problems

I recently rebuilt the front suspension on my 1968 a body barracuda fastback but my alignment guy says something is wrong because my torsion bar is rubbing on the tie rod. First he said it was my center link was put on backwards is it possible? Now he says he can't get it to align right that it pulls to the right when driven. This car came with a six cylinder and we put a 340 with V-8 torsion bars. what is wrong Thanks.
