I did it and posted in the "What did you do to your 60 this weekend" thread in the last 6 months.
Costs about $50. You just need a bluetooth dongle and FM Modulator. My radio maintains full AM/FM functionality and stock look. Everything is behind the dash.
I just have two front door speakers. I did upgrade those to modern speakers but stock size, note they have to be shallow or the window will hit them.
Sounds is OK. I can hear it with the windows down on the highway.

Scosche FM-MOD01 Modulator Play your iPod, satellite radio tuner, or other portable music player through any FM car stereo
I doubt the factory unit is strong enough to run 4 speakers, especially larger ones but anxious to hear how it works/sounds!
