Not having any luck at all either via Google searches or images, ebay anything. The part is from the Frog Re issue, its their 3x8mm step screw that fits into the upright, I can find a myriad of 4x... 3x 11,16 etc, self-tappers, you name it but 3x8mm or BD2 are yielding absolutely no results- any help, advice greatly received, cheers
