Installed my AOD tranny today but when we went to install the tranny cross member we found out that it wont fit ? It is like the cross member mounts on the chassis need to be removed and welded back in 2 inchs toward the rear. The car is a 1981 notch that had a inline 6 with what i believe to be a c5. Is it possible that the tranny cross member mounting location could be in a differant location on the chassis then 4 cy v6 or v8 cars?
