Original radios

[willy3486]

Here is one for the experts out there of chevy truck knowledge. The 1970 I have has a original AM radio. In 1970 did they have FM radios or even 8 tracks in the truck radios? The reason I was asking I was thinking about maybe putting one in it. I have a original underdash 8 track I plan to put in mine. But I thought if I have a am fm 8 track that was for the same year I might go that route. I have a few old radios to restore and I thought I might fix a fm if it was for that year. I bought out a original Delco radio repairmans shop years ago and have some items left.
