Restore a rusted-out rear shock mounting point with the Dorman - OE Solutions Suspension Shock Absorber Mount 999-805, a left rear upper shock bracket that welds onto the crossmember just like the factory piece it replaces.

This bracket sits at the front of the crossmember that also serves as the spare-tire mount and locates the rear upper shock.
