66 Valiant Signet Interior Decoding and Replacement

Hi all,
I need some help trying to identify replacements for the interior package of my car. I am attaching pictures of the interior as it came. It seems that none of the major replacement vendors reflect this pattern on any of their replacement options. Is my car truly a unicorn? Did the dealer do something unique? Were these interior options so rare that replacements were never produced? Is it worth the cost and effort to return this to "stock/show room original" I have gone through all the other mechanical things leaving body and interior to last. What to do, what to do?
