1. Here all the required parts needed to upgrade/convert the '82-'90 S-10 or S-15 to the later '91-'93 GMC grille. All the parts are from LMC Truck and only set us back $310.10 plus shipping. The later grille has a bunch of new mounting points, as well as moves the headlights down about an inch, so we picked up a new core support instead of jerry-rigging the old one. We did the job in one afternoon with no special tools; as a matter of fact we didn't even need to drain the radiator. Now if you have working A/C then you'll need to have it recharged after the job. Ours crapped out a long time ago and we have given up on the idea of fixing it.
