I want fog lights and I already have the cobra insert on My 5.0 1991LX. What do I need to put a Gt/ cobra front end on besides the facia and a light bar? Is there a support panel that is different? I would need the front fender spats to match the facia. Would I really need the aero kit under the doors and between the wheel wells? I suppose I am asking if I really need the whole cobra or gt kit.
