My grandpa had an 86 identical to this. Same color and wheel covers. Deep burgundy (almost black) vinyl interior, AM radio with front speakers only. AC was so cold it could freeze certain body parts off. He would let me tinker so I learned that the other stock GM radios mounted the same and matched the faceplate location. So I cut out the old one and left a rectangle for the new one. Aside from it being black instead of silver, it looked pretty good. The car got stolen and recovered, and was never quite the same afterwards.
