We need a new handle for the inside

This looks like our 82-030. I am afraid the inside pull is not sold on its own. However, so long as the hole spacing on your old handle set is 3-15/16" center-to-center, I am confident this can work for you. 

I'm confident that is 3-15/16", and therefore something like our 82-030 would be your best match. Let me know if you have further questions.
