If you haven't already, maybe try some of the old Nascar guys on as they ran the same Pure decals in the '68 season as seen in this cool bangshift linked clip also note Pearson's '68 HM Ford restored in recent years is sporting one in the pic below...

Also Jon, the racingsportscars.com site has little info or pics of your car included w/ the 67/68 listings of events it raced so you may want to post some updates over there...
