I have a 90 series 5 13bt but don't know what type?

Is it a savannah,GT or turbo2 can anyone help?

Its got the square blinkers on the front of the side panels in front of the wheels not the round ones behind the wheels so it is still a turbo 2 or could it be a savannah or GT?

Any comments would be much appreciated thank you RX7 Fans...
