M965 rear caliper problem

[66 triumph daytona]

I have an M965 I.S. rear caliper and when I mount it on the frame it doesnt have near enough clearance to fit a 160mm rotor.Its nothing to do with shimming,its the actual caliper itself,the wheel wont fit as the rotor is hitting the top of the caliper.Its like putting a 180mm rotor onto a 160mm caliper without an adapter.I ran M975 calipers on the frame with zero issues.Are M965 rotors slightly different dimensionally to the later rotors?

Re:

Problem solved-muggins fitted a front caliper to the rear..........Is M965 Just like M975 in that I can run a 140mm rotor on the rear whilst using a front caliper?

Re:

That’s basically how the ‘is’ standard works 20mm smaller on the rear.
