I need a piece similar to Product 26-223 except the distance to the outside of the legs is 7/8" and there is nothing between the legs.

Could you have something like our 26-154? If that won't work, please take a few pictures of your thumb lever and upload them here for us to see. It's important that we see the bottom prongs, especially.
