Car audio guy here....

I know there are purists that try to rule the car hobby with their "no modify" attitude but I have no issue installing an aftermarket stereo in a classic. I think it's up to the owner of the car to decide what's right and what's not. I'm 50 and when I was about 12 people started giving me old broken TV's and radio's to try to fix. I let the smoke out of most of those early ones (OOPS!) but it was fun. Later on I became pretty good at repairing them. When I started auto mechanics in HS in 1979 I started putting in stereo systems for the kids. Mind you that back then the systems weren't very high quality like we have today, nevertheless it was an improvement over AM (ancient modulation as we called it). Except for the low key system I put in my Cuda I haven't installed much in yrs. Nice to see you young and agile guys on the board. Maybe I'll learn something about the new stuff, LOL

Here's a (lousy quality) pic of my stereo install. You'll see I made a bracket to hang it under the dash rather than cut up my repro $450 dash insert. I polished up the original AM radio for looks and the aftermarket stereo can easily be removed without any lasting signs. I know there's the type that hide in the glove box and I would have used one of them but I got this one from a buddy at work for a super price
