Alright, I've now bought two of the same, wrong style fog lights it seems. Claiming that they are for my '89, however they are obviously different than the one that was left on the car. Unless the one on the car is wrong, but I highly doubt that.
Yeah I dont see a bracket on the one on the left. What you need is the one on the right to mount to the factory bracket. Foglights/brackets are the same 89-95 On Tbirds. So it may be for an 89 vehicle - just not a Tbird/Cougar.
