Hello, I recently picked up an ae86 levin hatch. I took it to a mechanic to fix the slave and master cylinder and they have said more concerning issues have arised such like a loose diff and control arms. The previous owner had written it is a Hilux shortened diff w/ disc break conversion. The mechanic said the car is unsafe to drive and would get red stickered if I was pulled over. How can I fix this? Sorry I don't know much about these cars.
