I am not 100% sure, but there is a 68 GTS in my area that I believe has original interior, and the bucket seats do have headrests. My car has buckets, but not original, they are high back seats. I am looking for a set of original cores, but they have to be reasonable, I am far from rich. Found a set in Ontario and the guy wanted $600.00. I will have to do with what I have.I cannot pay prices like this. That's rediculous.
