Factory part number 85135285: a side bracket supplied by GM.
It is catalogued under Brackets & Supports > Brackets. Varies by build: Without aev edition.
Brackets that carry load in shear rather than tension are sensitive to bolt grade, and substituting a lower grade is a common cause of elongation at the holes.
Handed to the carrier within one to two business days from our US warehouse, free over $59. Confirm the number before you order, because a near match will bolt on and still be wrong. Send the VIN if the old marking has gone.
