Is a Dimensions? Call them and ask. Or you can ask if someone in the FB Dimensions group can help. I do not have that one. I know a Dimensions to be helpful

You can reach Dimensions by going to their site, this page. Then click on "replacement part".

Simplicity is the parent company of Dimensions.
They don't list a phone number, so it would be hard to call them!
