Any guidance on my 1970 Duster plans

That sway bar mount will break off. Not where it should be attached. Not sure if anyone else already mentioned that.
It mounts over where the K frame diagonals for the frame rail. Right below where the strut rod is sticking through. You can see the two bolt holes in the pinch lip.
Agreed. The FF mount is further out by the front horn and is triangulated for better sway bar support. They (FF) also have bolt on lower control arm (LCA) brackets so you don’t have to use the factory arms with the brackets already on them.
