I would not put the radio guts in the small space, radio head would work, but I had an opening, like this in the dash of a chrysler LHS, nice opening, held disk and junk. Problem was no ventilation, so the radio , after a few transmissions, Yaesu 8900, would say "heat" an would not transmit until the radio had cooled off. Lived in Henderson, NV at the time and the space in the dash would not work, so went to split head operation, radio under the seat. Better ventilation and never saw the word "heat" appear again.
