The rear bumper on my '95 Suburban is rusting out. I can get an OEM replacement, but I like the newer Suburban's that have the trailer wiring socket built-in to the bumper. (on my current bumper I removed one of the license plate lamps, enlarged the hole and mounted the RV7 socket there). Does anyone know if a newer rear bumper will bolt up to a '95 Surburban? Or am I stuck with stock/OEM?
