There are 4 vertical projections (sort of like the keel board of a small sailboat) on the bottom of the headlight housing. You can't see these in the pic. If the retaining clips fit loosely, or some of the slots are broken (they are very thin, flimsy plastic), the projections will rest on the bumper cover tabs. If the retainers are nice and tight, there wil be a gap between the projections and the bumper cover. In the latter case, the headlight housing is hung in place only by the header.
This is a really poor design. Shimming the projections or bumper cover so the housing rests on the "shelf" would be much more secure. I've already shimmed my passenger side, and will do the driver's side tomorrow. It's an easy do-it-yourself job.
So what you are saying here is that when the headlight unit was put back on my Mustang that the metal retaining clips might have stretched out or even opened up the plastic retainer slots just a little bit giving the metal retaining clips a loose fit and causing the 4 vertical projections underneath the headlight housing unit to rest on the bumper cover tabs instead of allowing a gap to exist between the vertical projections and the bumper cover? In other words, the vertical projections underneath the headlight unit from the weight of the headlight unit rest on the bumper cover tabs. Is this correct?
Do you think that this is the real true cause of the gap between the top part of the headlight unit and the front pointed part of the front fender?
So, if the retainer slot is cheap flimsy plastic causing the metal retainer to have a loose fit inside it then nothing can be done to repair it except by shimming by putting something between the underneath part of the headlight unit's vertical projections and the bumper cover? Is that correct?
I haven't touched the metal retainers on the headlight unit, but the body shop owner told me that they are on tight. Is it possible that if the metal retainers are on tight that the problem might be the plastic retainer slots on the headlight unit? Could the plastic retainer slots have opened up or stretched themselves from the metal retainer clips being pulled out and then put back into the headlight housing retainer slots again after the repairs were done?
Also, is it better to shimmy something ONLY underneath the bottom part of the headlamp housing unit under the vertical projections and NOT underneath the bumper cover tabs? If something is shimmied under the headlight unit's vertical projections, will you be able to see what you shimmied under the vertical projections if you stand in front of the car and look directly into the gap between the bottom part of the headlight unit and the top part of the bumper?
Or is it better to shimmy something ONLY underneath the bottom part of the headlight housing socket? Which one of the two options is a better fix solution?
Also, I may be wrong about this, but I assume that nothing should be shimmied under the bumper cover tabs because if this happens, the bumper cover tabs will not be able to be secured into place on to the bottom part of the headlight housing socket...is this correct?
Please understand that I'm trying to cover all my bases towards finding the cause of the gap problem and I'm also trying to find the best fix solution here and that''s why I'm asking all these questions in full detail.
