Northrop T-38 Talon (64-0265)

Sam, this one is very likely USAF s/n 64-13265, c/s N.5694, with the 509th BW, 394th CTS, Whiteman AFB, MO. According Joe Baugher's information, 1964 was one of the rare years when the U.S. Air Force purchased more than 10,000 aircraft in one fiscal year. Hence, the last five digits of the serial number was truncated and 64-13265 becomes 64-265 on the tail.

This too, Sam... USAF s/n 64-0265 was assigned to a block of Boeing LGM-30A Minuteman missiles, 64-0001/0448, according to Joe Baugher's information.

I believe this was a AT-38C cliff can you clarify

Sam, that's possible... but Joe Baugher's information does not confirm such. All the photos I find of it designate this Talon as a T-38C and some show T-38A as type. I believe the Air Force has upgraded/converted most of the T-38A in inventory to T-38C status.
