I just purchased a repro radio from Classic Industries. It fits well although not as perfectly as OEM. It matches the original opening but there are two small control pushbuttons on either side of the Bowtie emblem. It has a classic look when it is turned off, but is bright green when it is 'on' to overcome the OEM graphics on the dial. It is a clever way to look stock, but still display the bands and such. I drilled a hole in the side of the glovebox to run my I-pod cable. The sound is very good and it precluded a CD changer or wasting the entire glove box for tunes. If you are looking for tunes it is a nice way to go. It is not OEM though if authenticity is your priority.
Keep em' rollin'
