I would try contacting Keystone to see if they can provide what you need. You can also check the classifieds to see if someone is selling one. You can then sell the dinette setup.

There are also aftermarket companies that sell furniture.

You can try:

https://rvfurniture.com/
Camping World
https://www.recpro.com/ <- has a large selection of furniture

Good luck
