Can't find these please help

Thanks for your patience during this busy season. I actually don't recognize your roller out-of-hand. It's design is a little different from what I've worked on before. However, I have a couple parts you can start with. I'd like you to compare the dimensions and pictures we show on each product's store page to your own part to see if any can work.

Start with our 81-157, and then maybe our 81-030 and 81-138.
