I'd like to replace my drop in Ritchie compass with a cup holder. My issue is the flange on the compass is 4 7/8" and most cup holders have a slightly smaller diameter. I'd like to cover up the screw holes from the compass if possible. Does anyone have a link for a cup holder that can cover that up? Someone posted a website a while back that had all kind of size options for cup holders. I cant find it unfortunately. Been looking through google with no luck either.
