The 5 np, 30 np and 75 np definitives from 1964 were overprinted in FILS and appeared in August 1966. See the 1966 list for the rest of the issues that were overprinted in FILS.
The used copy of the 75 fils issue overprinted a second time with 5 Dh.
My thanks to Khalid Al Omaira for supplying me with the images of these stamps.
