new style radio

Hi there,

I have a '72 Dodge Coronet, and i've been searching through the options to fit a radio. I have come across radio's of other mopars that might fit into my instrument cluster, but i would rather have one with usb or bluetooth capability. Retrosound radio's offer this in something that might fit, but in my opinion those things are way too expensive.

Is it possible to fit a new style radio into a dash without having to cut it up? I have been searching the internet for examples of how other guys did it, but there are not much pictures out there.

regards. Willem
