65 Valiant fender tag question about radio options?

Yeah that was the website I used to decode my fender tag. I didn't think my Valiant originally had a radio in it because I didn't see it on the fender tag. When I got the car of course someone hacked the radio hole for an aftermarket radio and installed some speakers in the back and it had some older cheap speaker in the front. Plus the wire hook on the fuse box wasn't hooked up the way the factory specifies too. I was wondering if it didn't originally have a radio would there still be a hole in the passenger side fender or would there be some kind of plug in it? Everything in the car seemed to be still original when I got it, besides the engine which I haven't understood why someone downgraded to a 170 from a 225. The carpet is even still original, the headliner is about the only original interior piece that's still useable. It's pretty much perfect. I bought a new speaker because I decided to install one of the correct Valiant lettered 65 AM radios I have but maybe I'll just put a delete plate in there. Amazing there's so little to go wrong compared to a modern car yet I haven't figured out why I can't start it using the key. But when I get it back on it's feet I believe it could still be a decent car to use for travel. No power steering, no power brakes, no a/c, no radio, and not many things on the dash to go wrong.
