Radio delete plate does not fit.

As I stated above, I made one that shape for my 66 B-Cuda. It fits in, and looks real good. They are easy to make.
If you wanted, you could driil too holes, where the radio knobs go, and use some short round head carridge bolts, make some big washers for the back, and bolt it on. Can paint it any color you want , before install.
