I guess a previous owner must have cut the doors up for speakers. Again, shows how much I know on the topic. Since the inner door panels are in good condition (other than the holes for speakers...) I imagine the body shop is planning on using them instead of replacing. I'll have to check with them before I make any decisions about speaker location.
Hmf, didn't realize I'd have so many things to consider in this resoration...I still get hung up on what encompasses 'original' and at what lengths I should go to keep it that way. I want the car to look genuinely like a classic, but I also plan on driving it and keeping it for a long time, so I want it to have 'creature comforts' such as a nice sterio, too! Ah, the tradeoffs...
