68 barracuda bucket seats-only one style??

Hi folks. I am starting to do the interior on my 68 fastback barracuda. What I cant figure out is this: Was there only one bucket frame available or not? I know you could order standard or deluxe upholstery packages but it is the actual frames I am wondering about. I want to order new bun pads but i need to clarify this before ordering. My buckets have factory headrests.
ALSO- who makes the best bun pad?
Thanks in advance,
Neal
