BB71,
I'm not that far along yet. The only head units I've been looking at are the Sony (I think) EXAD single DIN units. I liked the one with the screen centered and the buttons spaced equally on either side. After looking at my dash It looks like a DIN and a half would fit best with the way it is right now.
ntstlg,
I don't mind cutting on my car at all. The entire dash may end up getting swapped out for a complete fiberglass dash in the future, but for now, this is what I have to work with. Actually the center console is going to get some mods to it (handbrake and some assorted switches), but I would rather keep the head unit in the standard location. I don't want to have to look that far off the road to mess with the radio.
bullitt,
It could be an 8-track piece. I don't know for sure what they look like. Here's a pic. What do you think?
