I would look at using a 74HC series flip flop.  Runs down to 2V.

Or perhaps the ECG or NTE 9093D (an ECG-9093D is $1.25 on Ebay).  It's a dual flip flop.  You would need to check if the J and K inputs are usable in the 5065A.  I think it only has one pin per J/K and the 931G has two AND'd together.
