what is it out of .....in 68/9 and 70, almost every car line had a radio that was unique and did not interchange with other cars.
some go for 20-30 bucks and some models can get up to 300.+ dollars depending what it is. Some Am/FM units can go as high as a thousand dollars if not more.
The most valuable Am only units are the 70 only, Rally dash only units. ...68 and 9 barracudas are getting expensive too.
Most C-body units are good for parts ...unless you happen to have the oddball car it goes to.
