what is this called? receiver only
 

I have a 65 that is all original and still has the radio delete plate. I may add the original AM radio for looks but would like some tunes. I dont want to put something aftermarket in dash and have to cut on the dash....... So I was thinking at work our Case 621C loader has a small receiver about the size of a tri fold wallet. This would be perfect to mount in the glovebox or even under the dash somehow.

What are these called and what would be a good one to get? Dont want anything that rattles the windows, but want a clear crisp sound when driving. Anyone have one or had experience with one?

You could mount a deck in the glove box, but I'm not sure if you will find an FM tuner stand alone. I could be wrong, I've never actually looked.
