Thanks for your photos. Based on what I see here, you have either our Series 380 or Series 385, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

Sure, that looks to be a match for our 18-180. I feel confident this is what you want but as before you should check the dimensions to confirm they align.
