Please critique my home front-end alignment method

What lower ball joint is that? It doesn't have a steering stop at all. The "nub" circled in this picture is the steering stop. They vary a bit from one manufacturer to the next, but it should have one.
Thank you. What year is that from? I looked on Rock Auto and I don't see that nub on any of the 69 Dart lower ball joint pics... I got mine from ESPO.
