This is probably the most chosen to fit the GM Din and a 1/2 radio slots. Those new usually 379.00 I had one. Sound really great!!

 

Drop down tacky stuff? What on Earth are you talking about? The radio goes right inside the new A/C vent cover. Looks good and sounds GOOOOOD! After hearing it you will not mind how it looks as much.

 

A/C vent cover??? I realize that the second one will fit but the first one?? If thats the case, I have a Pioneer DEH-3400 sitting next to me

 

In the 92 model did the dash change? I had a 90 model and the aftermarket radio went under teh center a/c vents. Is your radio located in a different location? Either way all you have to do is get amounting kit unless you are using the din and a half radio.
