If you have an 82-90 S10 and want to change to the 91-93 grille, you have two options:  You COULD change your entire radiator core support, costing you a bunch of money and taking a bunch of time. 

Or, do yourself a favor and pick up these brackets!  These will drop your headlight bucket mounts to match the new grille openings, and take only minutes to install!
