Here are a few more pictures.  I made one modification that can be reversed in 5 minutes.  With a slight modification to the volume control I can play music via bluethooth and when unplugged it reverses to stock mode.  I followed this thread for the modification mp3 adapter .  Here's a before photo of the radio.  I think the previous repairman changed the filter capacitors before he realized the speaker was missing the cone.  After realizing he needed a new speaker I think he gave up.
Here it is before
