back brake drums q?

[baz-r]

what way round we putting the brake drum back plates?
im sure the sierra had the cable in from the front but looking at my car it looks better to swap the back plates side to side so the cable comes in from the back to alow a better cable route as there is not much room
also i cant see any problem in swaping them over
what or where is the cable route sposed to go? and whats the crack with mounts and supports for it?
