Scott,
So,I guess my question is, if you have a 91, why were you looking at the
E code headlamps?
They are 7" round aren't they?
Anyway, you could mount the lamps below the bumper, and the only
usefulness you would be limiting would be when you knock them off when
you hit something tall, when parking, road desbris, etc.
Go to E-bay, and search for Hella driving lights.
Got my Hella 500's there very cheap, but I mounted them up on top, where
they wouldn't get blasted.
