Death wobble

[RalphM]

No wishbone ball, their split, caster is about 6-1/2 to 7 degrees. The tie rod ends are new, and so are the wishbone ends.
As much as it might help, I'm hesitant to put on a stabilizer. My car is a traditional hot rod, built as if it would have been in the early to mid fifties. Something like that would be too much out of place.
Right now the newest part I have is a 56 steering box.
