They are structural in the sense that they locate a part precisely, even when they carry no crash load.
Brackets are replaced after a collision repair, when a mounting point has torn out of plastic, or when a rattle has been traced to a bent or missing support. A missing bracket is often the reason a console will not sit flush or a panel keeps working loose no matter how many clips are replaced.
Order by part number and by position. Left and right brackets are handed, and a bracket that looks identical to another may differ in the offset of its mounting hole by a few millimetres, which is enough to misalign the panel. Where the bracket is welded rather than bolted, confirm with us before ordering, because the repair procedure is different.
