I've been rebuilding a '67 Series 2A and had bought the Torrel disc conversion kit some years ago.

Now I'm trying to fit the callipers and I believe I've followed the instructions correctly but the calliper frame won't fit between the mounting bracket and the rotor.

Anyone else had this experience? I just don't see how I could do anything differently to mount the frame onto the bracket. (I know the brackets go L->left side and R->right side and the callipers go to the opposite side of their markings (i.e. L->right and R->left) but it doesn't change the fact that there simply isn't enough space to position the frame in the gap between bracket and rotor.
