Twelfty million of them available, try Amazon. VERY likely you will need to cut and splice a LOT of wires, matching the connectors is fairly unlikely unless a common brand. Very likely you will need a new display, also as these are frequently geared to work with specific conrollers and are rarely interchangeable.
So, get a generic controller and display, do some research to avoid having this problem in the future. All the motor needs is three phase and 5 Halls, assuming that is the connector in your picture, might be useful to post the connectors coming from the motor to verify it is not sensorless, the 5 wire connector would appear to be a Halls connector to the motor, but no verification that the motor has one, which would mean you need a controller capable of sensor-LESS mode, which not all are.
Your pictures show what your broken controller HAS, not repeat NOT what your existing motor, which you intend to re-use, REQUIRES.
If you require assistance and are in a hurry, make more of an effort to provide useful information.
Throttle and pedal sensor connections also could be problematic.
