52,
I've never heard of any other AD cab mountings on the conventional truck except for the 3 point (47, 48) and the 4 point
(49 and later) that are shown in the shop manual. I have never seen "solid" rear cab attachments like the front either. The rear mounts need to pivot or have some give to allow for frame flex. If these do exist on something it is news to me...maybe some other model.
