Model year '67 had the coach. I guess you can look in the sales manual. My '67 was a second week of July '67 build and had the coach on the belts as well.
I doubt you will find documented proof anywhere, but I have never seen anything different.
'68 model year also came with turquoise interior, so likely swapped at some point.
But feel free to disagree... I'd be the last person to say I'm the expert.
If they look nice in the car, leave 'em in.
