I’m a little confused here. The illustration in the parts book calls the rubber mount a “Rear Mounting Assy” in Group 4.081. I don’t see that part in either the page that Jim posted or the one from the Oct 1962 revision book that is available on line. The “Support” is the actual crossmember, and there are different P/Ns for 3spd, 4spd, and AT. The parts book shows a “Bracket (2 req’d) in 4.081, but the illustration shows them in Group 4.083 (which doesn’t exist in the listing pages). Also, the brackets are only used on the AT crossmember – the MT is hard mounted to the frame rails. Clearly this is a disconnect in the parts book.
