[Roadsters] Rear springs?

[Paul]

  My 1969 1600 suffers like many other roadster from rear spring sag.  It
has gotten to the point where I bottom out on almost every little bump, even
with newer shocks installed.  Other than buying new springs, comp or stock,
or having the old ones reached, is there a simple solution?  Some kind of
helper springs maybe that someone has installed on their late model
roadster?  I need to get some lift in time to drive down to the Mitty this
May.
