Daniel,
the best solution is to replace them with the power mirrors.  I know this
sounds crazy but I wrestled with the manual mirrors on our '83 for years
(multiple sets), and they were never nearly as functional as after I put on
some good used power mirrors.

You wouldn't even have to wire up the power mirrors.  Just bolt them on and
move the glass manually.

The problem of course is that power mirrors are expensive.  But like you
said, it's dangerous to drive with bad mirrors... I broke down and but ours
before moving to the city, where I considered reliable mirrors a must.

As a bonus, if you *do* wire them up, the power mirrors have a heating
element which can be wired into your defrost switch.
