USA Looking for a discontinued tile by Interceramic

[dlea2025]

I am looking for a couple boxes of tile by Interceramic in 18x36 Sparta Gray Polished. I have exhausted all avenues that I can think of, calling Interceramic in Mexico, online search, discount tile stores, etc., so I came here. We had a client that had to have their shower repaired, and unfortunately, we now need a couple boxes to fix the damages. Any suggestions would be greatly appreciated. Thank you!
