yeah it actually is that blue peice. i dont see how the insert would fit in there without it. i currently have some sort of an insert. its a big clunker and about an inch thick. its painted and not too sharp looking. its one peice of steel with the lip on it.
heres a closeup of what i have: note the PO's awesome paint skills

think i'll try to send an email to the guys at boese and see if they can answer.
