So here;s the crux of the issue with foxbody mustangs..the lower control arms are relatively parallel, however, the uppers are used not only to locate the diff front and rear, but side to side as well. Whenever you ask something to do two things, it never bodes well, in this case, especially once the car is lowered from the factory ride height, you will have 2 competing arcs..fighting each other, trying to keep the diff centered, This is why fox body cars go into snap oversteer on corner exit. Those opposing arcs are desperately trying to find center. If you make the mistake of adding a panhard bar to this cluster, you now have a 3rd conflicting arc, working against the 2 conflicting arcs that already exists, At this point you might as well weld the diff up solid. It is the opposite of having a "free" suspension, it is bound up in almost any direction.
We do however..have the answer to this..the redneck 3 link...
Locate a 1/2 x 1/2 Heim end, now this particular one is from a hardware store DO NOT use a Heim like this one, the real deal Aurora rod end is coming, I'm just using this to dummy up the install for now.
Once you mock everything up, I cut a spare upper arm, found some metal stock, drilled a hole in it, using grade 8 bolts..welded it all up..on the end of the discarded upper (trailing arm) control arm..
the somewhat finished product..
