You may be able to purchase the Kahrs America Cherry Miami here www.fastfloors.com/style_19732,0/K...
It has the same SKU number and name, but a different collection name. As long as the product looks the same, is the same height and length, has the same locking mechanism, and the same finish and gloss, it should be the same product.
I was unable to locate the Brazilian Cherry Rio de Janerio but I will talk to some of my contacts in the industry and see if I can locate them.
If you are unable to find the exact replacements, the same princinple applies as I stated above - Find one with the same height, length, locking mechanism, finish, and gloss and no one will be able to tell the difference.
Let me know if I can be of any more help!
