Code 863 is the only Vega green coded interior listed in my book .There is a * next to it stating it has " bucket seats with standard interior" .
The only cloth listed was in black or covert ? ( whatever that color is)
Bucket seats with "custom Interior" was available only in black , covert or tan . if that helps.
You probally should ask one of the Vega guys here that has a Dealer order book.
You might have a rare car there, not much greens were made with green interiors, my guess?
You have a pic ?
