I have a 1995 Chevrolet S10 LS Extended Cab 4×4 Pickup. I have been driving it for 2 years now. One thing that has been bothering me is the sliding rear window. The latch has been broke since I first received the pickup.
I FOUND a part number for the latch. All it took was a look on the inter-webs. The GM part number is 12543916. The latch fits Chevrolet S10′s from 1994-2003. I paid around $20 with shipping.
