This is a 1:43 TOYOTA SPRINTER TRUENO AE86 cover for a Dr!ft rc car. https://www.sturmkind.com/
I've added a cover to secure the front wheels as it won't fit with the regular front radiator that comes with the normal cars.
Unfortunately I can't remember who was the original design for the car stl. I'm happy to put in your details if you recognize your original work and come forward. I've only carved the car out and shrunk it to 1:43 adding spoilers and fixing the rear and other details that were damaged.
