Hang ten or Spirit of 76?...

I bought some bucket seats at a swap meet last April. I was under the impression that they were Spirit of 76 bucket seats because of the red white and blue stripes down the center? But when I research I find that the 1974 hang ten also had this kind of striping on the interior? I want to put this up for sale but I don't know what it is for a fact or if it could be for both? The bottom cushion pieces are dirtier than the backs and of course the upper headrest portion is the best. I don't know if it could be deep cleaned and restored or what? anyways any information anybody has on these that's definite would be great....
When I had the seat reupholstered I just had him save the center portions...
Thank you...
