Brake shoe orientation

Do I have this right?  I'm doing the rear brakes on a '72 Midget.

Using the illustration in the Moss manual, the front shoe has the longer
area without lining to the top and the rear one has it to the bottom.

Also, any quick fixes to the adjustment?  I've got brand new shoes and
brand new drums, but the adjuster will go all the way in without locking
the drum, like I've experienced in the past.
