Which tie rods?? 1968 Dart

Rebuilding the front end on my 68 Dart. It has a 73 and up idler, pitman and center link. It has 73 and down lower ball joints because of the Kelsey Hayes disc brakes. Most show 1962-1969 as ES319R and ES319L and 1970-1976 as ES401R and ES401R Mancini show they change over at 1968 and up?? Any idea which ones to use?? This is the front end that I have. Thanks.
