67 Jack dating

[Jeff Bukowski]

Just received a 67 reproduction jack from a vendor. I requested a date stamp of C7 and it came back dated 7C. The person who stamps the date says the sequence is always year then month on jacks. I was thinking a month-year format for some of 67 then maybe a switch to year-month. Any thoughts or comments????

So March 67 and earlier (month-year), May and later (year-month). I need someone to join in with an April jack to see when the change happened.
Thanks

Re: 67 Jack dating

I can't give you an answer to a change over but I have a June built 67 and this is what I believe is an original jack to the car. A B 7 date code. My point is that it conforms to the 6 month rule.
