After market radios

[Rookie]

Thanks for the suggestions on shops that may have them. I tried a stereo shop and they told me they don't sell them cause I may want to trade mine for another better model (steal it is how I read his comments). I had the dash trim off up to the radio. I guess the way they mount them locks the trim in until you pull the radio out. So it has to be pulled.
I'll have the daughter check out the Wal Marche and see if they have them and if not Ebay looks like the way to go...

Thanks guys
