Bolt Grade Change
I was sorting through some hardware I recently had replated and came across these three bolts. Looks like it went from 8G to 8 8 to 8.8. A 67 911 has the 8G, 10K, etc. bolts, a 74 VW has 8.8, 10.9, etc. Looks like only KAMAX has the interim 8 8 and 10 9.
Let's try to figure out what year this change happened. Definitely between 1967 and 1974.

I found it. The new grade draft went into effect October 1966 with production starting July 1968.
