First of all the 1979 GM cars used R12 Freon and that's no longer available.
You can upgrade (upgrade??) to R134a but I would recommend that you replace
the drier. While the system is open you could blow the condenser out with
some low air pressure if you want to. Disconnect the hoses at the condenser
first.

The O-Rings should be changed BUT the hoses don't need to be unless one
is damaged. The oil used in the R-12 systems soaks into the hoses and
provides a barrier itself. Even flushing doesn't clean the system to the
point where the barrier is gone.
http://www.delanet.com/~pparish/hose.htm just one site with info. (also
a good site for a LOT of info on AC)
