Thanks for all the information guys! The PHS documentation is a little confusing. On the order sheet under the head restraint column 57, the add number is only the numeral two. On my build sheet under column 57 is the number 1. I have read other posts in which people have said that the number on the order sheet and build sheet can be different (maybe based on the number of beers the guy at the plant had at lunch!) But the Head restraints, if they are original to my car make the cars build even more rare.
This has become important to me recently since I just sent the car off to start its restoration last week. If the seats are original to the car, then I'll keep them. I thought if someone had thrown in a pair of 69 seats, I could be free to upgrade them to something newer.
