I see a few guys running their brake stuff. I remember being put on hold for a long time when I called them. Now they have a full chassis for 69 nova. I heard it handles pertty well. I would ask do the A arms cure any of the geometry issues on the first gen. What kind of bushings are in them. With the load the parts take you don want some cheesy parts.
I bought a set from this guy, great shipping and VERY nice product, Billit cross shafts, fully assembled I am happy with them, I could not update the stockers for that price-Chris
