Mine has an original radio for looks and a cd that i hung under the dash right above my console. Works pretty good and I didn't have to drill any holes or do any cutting.

You could also try getting an original radio refurbished and then get a fm modulator that will send a signal from a cd player/cassette to the stock stereo. I buy all my stuff from http://www.crutchfield.com/ they should have a "knob" style radio that'll fit.
