Factory part number 86549494: a f (s)bracket supplied by GM.
GM F (S)Bracket (86549494).
Rubber insulators isolate vibration, and a worn insulator will make even a new bracket feel loose within a few thousand miles.
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.
