Looking for newer (higher version) NP NCL coaches

[Forester1]

Hi! I am looking for Northern Pacific green-on-green passenger coaches. I would like to build a "North Coast Limited" train circa 1960s, and I have some great locomotives from TrainzForge, but the only passenger coaches I can find are version 2.9, and they kind of show their age. Does anyone know of any of these coaches in a higher version? Thanks for any assists!
