The cab mounting hardware changed over the lifespan of the C-cab. 2R and 3R had short, heavy springs on a couple of the mounts; later ones (unsure of when -- don't have access to my parts books) used rubber donuts. The 49-56 parts book lists the parts in the cab body section, but has no illustration. The later books have illustrations. All four corner mounts are different in some way.
