Application for these Goodyear Polyglas 14 x 7 F70-14

[XXXGoldL34M20]

Changing these tires out on a customers 1970 Chevelle SS, which the last owner ordered the incorrect tires.
Wondering what the correct application (Cars) wore these Goodyear Polyglas 14 x 7 F70-14 Tires without the call out of the size.
Found A photo of what looks to be a 69 Camaro?
But Obviously not correct for 70 Chevelle SS.

Let me know your thoughts & Thanks in Advance.
I'll be taking these off soon but want to know for sure the application before I sell in the Classifieds here. Tires have less then 100 miles on them.

*Kelsey Only states these are for 1967 to October 1969*
