1973 Headlight doors not working and Torsion bar adjusting

[Chad Zeilenga <chadzeilenga@xxxxxxxxx>]

Recently my 73 Imp has been making a slight buzzing
sound coming from under the dash.  It appears to be an
electronic buzzer of some sort and only comes on when
I turn on the lights.  I also noticed that the
headlight doors do not open fully when turned on and I
have to manually push them up a little.  I know the
two are related but does anyone have any ideas before
I go looking at the system.
Also, the front end of my Imperial seems to sit a
little low.  I would like to adjust the torsion bars
but have been warned by some that as they get old they
fatigue and can break easier.  I do not know if they
have been replaced in the past or if they are
original.  Has anyone here had much experience with
adjusting them.
Also, what would be a recommended adjusting
proceedure?
