Rocker arm assembly install

As far as the shafts. One side the notch goes to the back of the motor the other towards the front. So I need to be sure what they mean when they say left or right.

Your drawings were great. Thanks.

look at it this way
if you stand on the driverside, put the notch to your left, and down

if you stand on the passengerside, put the notch to your left and down


you'll notice on is to the left, the other to the right, doesn't matter which one you call which

(of course, this only work is the notches are correct)
