Toyota Guys

This is a rather dumb question, but here goes...

I had the shafts out of my Toyota rear axle and when I put them back in I didn't know what orientation they should be in. My reference is the bleed valve and brake fluid input. Should this part be at 12 o'clock or what? Is there a left side and a right side or are they interchangeable? Where does the parking brake lever go. I am looking from under the truck at each side, so this is how I am referencing my clock positions.

Thanks.

the part where the emergency brake hooks on...that should behind the axle tube and somewhat above it....if you were looking at the hub as if changing a tire....

i'd say 2 o clock and your bleeder is 12 if i remember right
