Those pictures look nothing like the ones on my TF.
I Just sold a pair of fog lights and brackets on ebay
The outer plastic surround is screwed/bonded to the inside of the bumper, and the lights atached with three screws/bolts.
The adjustment is on the lamp itself, like the headlights.
The MGF and MGTF lights and brackets are completely different from each other
I do have a pair of new brackets also!
