I hope someone can answer a simple question for me or more so even offer the part for a fair price. Lastnight I was installing angel eyes AIB3 that I bought at the meet and when I was pulling the headlight unit out. One of the small metal retaining clips looks like " [ " fell off and into the engine bay. I believe theres like 1 on each corner of the headlamp unit (3-4 all in all) holding the two parts of the glass headlamp together. I am concerned it might affect the longetivity and durabilty of the unit itself??? Sucks when you have OCD and you want everything perfectly installed I've tried real oem but the part is so small that it is not mentioned anywhere. Again it literally looks like a [ symbol and its made of metal (steel look) and is probably about 1 inch n it goes on the corner edges of the headlamp.
Thanks for your time in advance!
