Remove the outer headlamp chrome rim.
There are 3 screws holding the inner chrome rim.
Remove one of the screws and fit one of the brackets so it is against the side of the chrome rim.
Repeat this for the other 2.
The outer chrome rim then fits over the brackets so they protrude between the two rims.
The stone guard then clips into the brackets.
There is always about 1" or so between the glass and the guard.
However......
If you have aftermarket headlamp bowls, the screws might not be the same as the original Lucas. For example, the Wipac plastic bowls have the screws coming in from the back so you cant fit the brackets.
If your car is an Mpi, you also won't be able to fit them because they use the Wipac units as original equipment.
