Hi, I'm a newbie with a 72 with a 350 and SM 465. The guy I bought it from had a Spector tow bar put on it and flat towed it everywhere with the rear driveshaft disconnected. I've had a mechanic say there's no reason for the disconnect on the shaft with the transfer case in neutral, that the transfer case won't slip into gear, and the way it's built there's plenty of oil moving around to keep things oiled and cool. Any advice/experience you have would be most appreciated. Frank
