I'm putting a project 72 back together that isn't mine, so I have no idea how some of it came apart. Since I have the rear window out I thought addressing the speakers now might be a good idea. I have two replacement rear speakers and a new deck cover. The rear window looks to be super close to the speakers so I'm wondering how should a person install them for future removal if necessary. Should I mount them from the bottom and let the deck cover sit flat over the holes? Or should I mount them top down, cut holes in the deck cover and use speaker covers to sandwich down?
