New member here, I am awaiting delivery of my new (to me) 1966 Chevy K-10 long box fleetside. The Previous owner tells me it will need a new radio. Not sure if that means that the radio is dead or removed. I am a competent installer but I'd like to know if there are any serious issues I should consider before trying to install a modern AM/FM/CD/MP3 head unit in one of these old trucks.
