Stereo system notes :
Sizing : All stereos
are the same dimensions 82-02, with the exception of the 93-96 Camaro
stereos, which are slightly larger. Most units will physically fit
most 82-02 F-cars and others.
Brackets : The
brackets that mount the stereo to the console & dash differ between
years, but are interchangeable between stereos. 93-02 Firebird
& 97-02 Camaro stereos have non-removable brackets.
Plugs : The largest
difference in changes from 82-02 are the plugs and connectors. Most
units will work in any year if you change the connectors.
82-88 stereos (left
picture below) use the larger connectors with an additional 2-pin
connector for memory.
The 89-02 stereos (right
picture below) use the smaller connectors, along with a smaller antenna
95 and newer stereos
equipped with a factory CD changer have an additional connector on the
rear (right picture below, plug on right).
