Hi
These look more like rear cams to me. As far as I know the shaft of the rear levers should be to the rear of the backplate, slightly below the centreline with the lever facing more or less down and the cable passing underneath the axle. This places the levers roughly at right angles to the cam, so the the cotter slots will be roughly parallel to the cam. As with the fronts, the Left and Right cams will then have a different small offset from parallel.
The front cams have cotter slots roughly at right angles to the cam, again with different Left and Right offsets, as I described in a previous post.
The situation isn't helped by some confusing published drawings. The top left section of the Austin drawing shows this, but looks odd presumably of the drawing convention: https://archive.a7ca.org/collections/tec.../td0010-2/ Woodrow's drawings H12 and H13 show the adjuster at the top, which is incorrect. On top of this, the backplate is held on with 4 bolts which has allowed owners to reposition them over the years !
