I was looking at my GVW plate and it lists the GVW of my truck at 5000 lbs. What I don't quite understand is the '65 Truck info from GM Heritage Center lists the following: GVW Selector 4100 lb Standard 4400 lb Standard 4800 lb 2000-lb rear springs 5000 lb 2000-lb rear springs So what's your GVW plate have stamped on it?
