sorry, no pics, and i don't have it with me to measure, right now. it came in my gasket set with my remanned longblock. it's a lightweight metal plate, roughly 1"x2.5". it is divided into two rectangles with a 1/2" or so hole in each. one hole has 2 little prongs on it, like the piece is to be folded along the crease and held in place with the bent prongs. my best guess is that it is for restricting flow of air or fluid, but i have not seen one before. i hope my description is decent enough that someone knows what i'm talking about. thanks.
