Go to any parts store.Look in the light section and you will find a set of rect. fog/driving lites.They are very generic and have 2 screws that hold the lens on,and a plastic revolving type of adjuster,I think Blazer makes some.

They will fit w/o cutting plastic(gotta pop out the factory covers).Look on Lisa cardomain site below for pics.....
should be some.
