Searching for Nyc7830

I'm confident that we can supply a match for your roller, but we cannot ID what you have from this photo. What you have here is just the inside portion of a complete roller assembly. In order to find a good match, we need to see the outer housing, too, which is probably still in the door. If you can remove that and show me the whole assembly put together, we will do our best to find a good replacement option.
