Hello guys... I recently bought a 1988 toyota supra. I bought it of a guy that had it abandoned at the back of his yard (and as you can imagine the car is really beat up). The car has a removable roof which does not work any more due to some missing screws. I live in Los Angeles and im afraid to drive to places and park it.They might steel the car, due to the missing roof. I wanted to install a kill switch in the mean time i fix the roof, but i need more info on this matter. Can any one give me any references, suggestions, or anything that can help me out, me and my supra will greatly appreciate it.. thanks!!
