Used impact sensor mount bracket. This bracket attaches to the top of the radiator support, just under the hood latch, and holds the front SIR impact sensor. The factory spot welds these brackets to the support as well as 2 bolts from underneath, so you will need to weld this back to your support. Fits the following:
90-92 Camaro (all models)
90-92 Firebird/Trans Am (all models)
