Radio delete plate does not fit.

The radio from a 64-65 has the same spread as a 66, but the unseen part behind is quite different....only a 66 or newer ( yes newer) will clear the heater switch. The opening looks correct. The cluster is major different, so I wouldn't be surprised to find out that a 64/65 doesn't look right, but if the delete panel is early A Barracuda.....should cover
