modern sound for a Duster

Hey guys and gals, new to the forum, but a third generation Mopar enthusiast. Anyway, I have a 1970 Duster 340 that I will hopefully begin restoring/modifying this fall. My question involves sound systems. I want to keep as near an original appearance as possible but I want a modern stereo/CD/mp3 to go in the original rallye dash with as little cutting as possible. Any ideas? Thanks guys and gals.
