Those are all good points, Thank you. I am going to give it another good look over. Don't want to buy new parts before I know which ones are broken. I can say it is on a flat surface, that the cab mounts are all relatively new, & I have measured the distance between the garage floor and the front of the frame and the driver's side C-channel sits lower. The tires are the same size and of relatively equal pressure. I have been unable to seperate it further to determine if it is bent frame, a busted coil spring, or worn suspension parts. These old trucks have often times been through more than they let on.
