Possibly the IAI (Israel Aircraft Industries) Kafir.  Several were purchased from Israel for training purposes, as they could do good imitations of the Mig.  They're  a hybrid aircraft combining the Dessault Mirage body  with the F4 j-9 engine.  The Mirage body was considerably lengthened to accomodate the engine with a new air intake added to thetail assembly.  In a later version, whisker stabilisers were added to the nose  assembly.
