Forgot to buy back plating for my LC wool pads, what size do I need?

I don't recall what size my wool pads are, but they're from LC. What size BP would I need for it? the 6'' or 7''?

They are probably 6.5" pads, so I'd venture the guess of 6" backing plate.

Just realized my pads are 7 1/2'' so I'll be picking up the 6'' back plating
