Please let me know if you can find these vinyl stops and what the cost will be.

Thanks for contacting us. I'm having trouble identifying what you need based on these pictures. Your third picture is actually the perfect angle, but the flash of your camera makes it very hard to make out its shape. Could you get me a clearer picture from that same angle? Can you also provide your dimensions? That would be a huge help.
