I have a loading door glass that came out of a 1968 Superior Cadillac Rescuer ambulance. It measures about 19 inches in height and 42 inches across on one side and 45 inches across the other side, these measurement were taken on the inside of the glass, so they are straight with no measurement of curvature. No doubt, this glass will fit other years. If you want it, please let me know. FREE to anybody who can use it, but shipping cost must be paid.
