Anything wrong with this?

? can the steering linkage be interchanged from 72 down to 73 up a vise versa with out problems and is there a difference in the center link on the 72 down s/6 an v8 some say yes some say no doing a v8 swap using a 73 up k member on a 70 and the steering is perfect on it so if the linkage will inter change i may just reuse it on the newer k member if i can any advice on this thanks
