I just bought a radio from a guy on e-bay. He advertised it as from a 67 camaro. It has 3 wires coming out of it but not from a pigtail. One wire (yellow) comes out the drivers side of the body. The other two wires come out the back. There is a tag on it that has the model number and serial number but you can not read the numbers. The tag has the manufacturer name Automatic Radio. On the side there is an ink stamp of CMR 7151. The dial face does not have delco on it. The numbers start at 5.5 and go to 16. The bezel has casting numbers of 54D5107 142007-040. Is this correct for my 67 camaro.

Sounds like an aftermarket radio.
Might fit in your 67 Camaro, but it would not be original factory correct.
do you have a picture?
