Yes. My typo should have read 1-7/8”. I always thought the Type 14 and 16 designations were 16ths over the 1” base. Hence 1+14/16 and 1+16/16ths.
I am happy to be corrected with your metric dimensions but believe Girling were still imperial in the 60’s.

>> BJ8 used Type 16 calipers and also 3/4” rear cylinders. That is also good but gives slightly longer pedal travel. BMC compensated by increasing the Master cylinder size and adding a servo. Not strictly necessary but gave good results with lower pedal effort.

>> If you stay with 1” rear cylinders the rears will lock under hard braking and potentially cause you switch ends. Not recommended.
