re: Rear Sway Bar

  I don't know about the 1/4 elliptic spring cars.  However, there was one on 
my '73.
  IMHO...
  Only use a very thin one and then only if you also use -at least- a stock 
diameter front bar.
  (I have also done a fair amount of autocrossing in the past so have at least 
some experience of handling a somewhat twitchy car.)
  Have never tried a panhard bar but from what I've heard here before it may be 
better bang-for-the-buck than a rear sway bar on a street car being driven 
"spritely". :-)
