The earlier sway bars (pre 72) had the sway bar mounts outboard of the strut rod, like shown in Dennis's picture. the 73+ control arms have the sway bar tabs mounted inboard of the strut rods. I found this out when I bought a Hellwig sway bar for my 72, but I then installed QA1 lower control arms, which use a similar mounting location as the 73+ arms. I bought a 73+ sway bar and it fit just fine after adjusting the length of the end links. Here's a picture of the 73+ mounting.
