early 70's
What do I win

 

early 70's.

Very likely. I have an original parts box with that same GT40 image on it date printed 1966 so sometime in that era and into the early seventies.

 

Yes, I have a set of BF-42, unopened for my FE 390, Believe late 60's. I also have the Rotunda Cleaner & Wax, unopened for my car.

 

Very likely right after the Motorcraft brand was "reintroduced" in 1972 as the plugs are still Autolite and not Motorcraft-branded. Probably '72-73.

 

Yep, Ford was forced to sell Autolite in 1972 and Motorcraft was the new name for Ford parts after that so early to mid 70's would be my guess since the container says Motorcraft and the label says Autolite spark plugs.
I think Bendix bought the Autolite name.

 

I concur. Early'70's...'72-'74 Probably..
