Running change to big block transmission mount

I am trying to determine the date of the changeover from the 1967 style mount (top) to the 1969 style mount (bottom).
Any input would be appreciated.

I am working on a '67 390 GT which had a scheduled build date and actual build date of October 31, 1967. It has the early style cross member with the shorter slots and was assembled at Dearborn Rouge plant.

The transmission mount evolution for sure happened in later 68 production . Sorry to say I do not have anything close to enough data to say when in 68 production.Hopefully this discussion here will help get closer. It was not anytime in 67 production or early 68 based on observations by many including myself.

I have a Dec 66 GT500 with the short-slotted cross member. All the long-slotted units I have seen have 390 STD 250 on them. They seem to be primariy found on 69-70 vehicles. Perhaps they're extremely late. Jul-Aug.

We'd need today's full moon to make out anything in that pic.

Sorry, that is the best picture I have of that car.
All you need to see is the indented arc on the passenger side to tell the difference. The earlier version does not have that.
