Sorry, did not mean to "cut you off". I was just picking up on your original post about "early style" and JohnZ's reply about NOS.
Actually, I was referring to the replacement keys that are NOT "early style". (You really have to hunt for the "early style" in their online store.) They give this disclaimer in the online store for their "replacement keys": "Note: 1967-68 keys are later model design and will work but do not resemble the early model Briggs and Stratton keys. Genuine GM Replacements."
But you guys had already covered it, so I dropped it from the post.
That does explain, however, why many of us are walking around with E/F keys to start our 68s. I was given two sets of keys for my 68 by the seller. He said, "One set is the original." But both are actually E/F replacements.
Thanks for reminding us of Rich's report. It's interesting that keys changed that much in the late 60s. Sign of the times...
And thanks for an enlightening thread!
