When I bought my '81, in January '82, it had no
radio, no speakers, no antenna.  They had
'82s on the lot, but I didn't want them--they
had carpet and I wanted the '81 with rubber
mats.  Still the correct choice....

When I had the 3rd party shop add a tape player--
anybody remember those?--cassette, not 8 track--
they put the antenna on the passenger side.
