Bucket seat cars were always custom interior cars, and therefore would have the deluxe door panels - parchment in '68-9 and woodgrain in '70.
Bench seat cars could also be had with custom interiors, which included different seat covers, and the other items you mentioned.
BTW, the car should have a spare tire, I'm pretty sure they all got one even if the car was bought with the intention to race it. Nice car, love the black on black with black wheels!!
Not a real pretty pic, but it shows the parchement door panel with the bucket seats on my '69 before I bought it.
