Just saw this thread.....
The lower plugs with the large letters are correct for your 69 assuming they also say "Powertip". The small lettering plugs were made during the transition from Autolite to Motorcraft plugs when Autolites began a different numbering system. I have 4 different versions of Autolite BF-32 plugs. I'm guessing a lot on the dates but listed in chronological (?) order they are:
1. Star logo, 1967 and earlier
2. Large Autolite lettering but NOT Powertip and NO star logo. Only ever seen a couple of these, guessing there was a very narrow production window in 1967?
3. Large Autolite lettering, Powertip. 1967 - ?
4. Small Autolite lettering, Powertip. No idea when these were produced but they originally came in a box that said both Autolite AND Motorcraft.
Would love to hear if anyone has more info on this subject...
