Front Front shackles 1959

Not sure I have anything valuable to add.
in both pictures the front ball joint on drag link looks like it is twisted, an issue with that?


The original TF steering box location behind the axle also had a pretty short drag link, putting the drag link pivot in front of the rear spring pivot. As the spring flattens the axle will move away from the fixed shackle and the drag link will force in a bit of right steer. Same things happens with your setup. Based on looking at some pictures the factory built in some downwards angle to the drag link so that as the axled moved up in it's travel the drag link arc of travel would add some left steer to counteract. With the box in front you'd need to angle the draglink up like in the first photo.

so IF you get darting to the right on braking try going back to the steering arm in first picture and see if it reduces the right dart or changes it to left dart.

If it darts either way randomly or following road camber, check alignment, maybe add some caster with a shim. You have power steering now so can deal with more caster.
