fifth indie nominal budged curlers elite purple legless aorta crochet equate mummy engine nuns stunt sighs off torso coroner river seen prep dearest sauna treat ease dented lowly memes turtle tortoise entree radar sucks
And indeed, ...
... the replacement letters give us the instructions above, but in fewer words. They read:
