Thanks for all the ideas. I've seen some of the 'retro' replacement units. They look good, but I haven't seen one that does everything (CD/MP3/WMA). I'm not turning this into a window-rattling buggy, but I am hoping for good, clean sound, and a lot of it when the spirit moves.

I've considered both console mount and under-dash. There's room for both, but I worry about temperature extremes in the winter. This thing has a great heater! and really pumps out the BTUs. The headliner console is something that I've not considered.

I plan (at this juncture) to keep the bench seat, although I'm not sure if I'm going to try to match up the original when I recover it or go with a whole new interior theme. I guess for now, I'll try to find a mounting that will work either under the dash, or on the console, and then work to make it look really pretty in time, when I get the $$$ for a real face lift.
