According to new 60 series brochure in front of me, 9660, 9760, and 9860 all have same threshing-separating dimensions. Threshing diameter is 30 inches, separating diameter is 33 inches and total length of rotor is 123 inches. Even range of operating rpm is same on all three models at 210 to 1000 rpm. New smaller 9560 has different dimensions. Hope this answers your question.
