What AM/FM Radio will fit a 72 Demon

Also, lots of other options avaiable these day other than fitting in the orignal location or hacking up the dash. Some have just mounted a bluethooth amp under the dash and using their phone. I've got a round marine guage pod radio mounted with my other guages under the dash. Although I made my own, I think a member here was also selling a plate to mount two 3.5"/4" speakers in the orignal location.
