Things like this is why this book is so valuable.
For example.Although the late (bigger ball joint) will work with the early lower control arm a little grinding may be necessary on the steering stops of the bigger ball joints,because the early and late control arms are shaped differently in this area.
also the early sway bar will hit the 73-76 calipers.You can fix this by swapping the spindles to opposite sides,and running the calipers on the back of the spindles.
