towhook cover table



Hi e90post,

I'm about to buy a towhook cover for my E93 from the internet and I was wondering what's the point of this strange table on the back of each towhook cover. They seem to vary piece from piece. Does anyone know what this table and the dots on it signify? It's a super strange question (I only ask super strange questions anyway :) ), but I'd like to get the right part.
