Unfortunately, the ones for '68 are a one year deal. :brickwall:
I remember I went through this back in 1996 when I had my seats redone.
They were missing after the seats were redone sometime in the 80's by the original owner.
I found mine in a goat-shit infested junk yard down in York, PA. The car stunk from the goats the guy had running around the yard, it was unreal.
I cut them out of a 1968 Satellite wagon. I am sorry to say, you might have a tough time. I have never seen them repopped and 90% of restored '68 cars don't have them on the seat backs......
