The 1970 B body AM FM (# 2884753)is unique . No other radio looks like it.

The lense(which is blacked out across the top) push buttons (which have squares facing up ) mounting bolt hole locations on front of housing (knob shafts not threaded) are all unique features to the 70 B.

By the way, the radio pictured above does not have the correct push buttons. It looks like someone swapped the tuner mechanism, buttons and all , with an A body unit.
